Wealth usually refers to money and property. It is the abundance of objects of value and also the state of having accumulated these objects. The use of the word itself assumes some socially-accepted means of identifying objects, land, or money as "belonging to" someone, i.e. a broadly accepted notion of property and a means of protection of that property that can be invoked with minimal (or, ideally, no) effort and expense on the part of the owner. Concepts of wealth vary among societies.

The Anthropological view of Wealth
Anthropology characterizes societies, in part, based on a society's concept of wealth, and the institutional structures and power used to protect this wealth. Several types are defined below. They can be viewed as an evolutionary progression.

A rudimentary notion of wealth
Great Apes seem to have notions of "turf" and control of food-gathering ranges, but it is questionable whether they understand this as a form of wealth. They acquire and use limited tools but these objects typically do not change, are simple to re-create, and therefore are unlikely to be seen as objects of wealth. Gorillas seem to have the capacity to recognize and protect pets and children, but this seems less an idea of wealth than of family.

The interpersonal concept of wealth
Hominoids, including all human ancestors, seem to have started with incipient ideas of wealth, similar to that of the great apes. But as tools, clothing, and other mobile infrastructural capital became important to survival (especially in hostile biomes), ideas such as the inheritance of wealth, political positions, leadership, and ability to control group movements (to perhaps reinforce such power) emerged. Neanderthal societies had elaborate funerary rites and cave painting which implies at least a notion of shared assets that could be spent for social purposes, or preserved for social purposes. Wealth may have been collective.

Wealth as the accumulation of non-necessities
Humans back to and including the Cro-Magnon seem to have had clearly defined rulers and status hierarchies. Digs in Russia have revealed elaborate funeral clothing on a pair of children buried there over 35,000 years ago. This indicates a considerable accumulation of wealth by some individuals or families. The high artisan skill also suggest the capacity to direct specialized labor to tasks that are not of any utility to the group's survival.

Wealth as control of arable land
Irrigation and urbanization, especially in ancient Sumer and later Egypt, are thought to have triggered a shift that unified the ideas of wealth and control of land and agriculture. To Feed a large stable population, it was possible and necessary to achieve universal cultivation and city-state protection. The notion of the state and the notion of war are said to have emerged at this time. Tribal cultures were formalized into what we would call feudal systems, and many obligations were assumed by monarchy and related aristocracy. Protection of infrastructural capital built up over generations became critical: city walls, irrigation systems, sewage systems, aqueducts, buildings, all impossible to replace within a single generation, and thus a matter of social survival to maintain. The social capital of entire societies was often defined in terms of its relation to infrastructural capital ( e.g. castles or forts or an allied monastery, cathedral or temple), and natural capital, (i.e. the land that supplied locally grown food). Agricultural economics continues these traditions in the analyses of modern agricultural policy and related ideas of wealth, e.g. the ark of taste model of agricultural wealth.

The capitalist notion of wealth
Industrialization emphasized the role of technology. Many jobs were automated. Machines replaced some workers while other workers became more specialized. Labor specialization became critical to economic success. However, physical capital, as it came to be known, consisting of both the natural capital (raw materials from nature) and the infrastructural capital (facilitating technology), became the focus of the analysis of wealth. Adam Smith saw wealth creation as the combination of materials, labor, land, and technology in such a way as to capture a profit. The theories of David Ricardo, John Locke, John Stuart Mill, and later, Karl Marx, in the 18th century and 19th century built on these views of wealth that we now call classical economics and Marxist economics.

Other Concepts of Wealth

Global wealth
Michel Foucault commented that the concept of Man as an aggregate did not exist before the 18th century. The shift from the analysis of an individual's wealth to the concept of an aggregation of all men is implied in the concepts of political economy and then economics. This transition took place as a result of a cultural bias inherent in the Enlightenment. Wealth was seen as an objective fact of living as a human being in a society.

Zero-Sum Game
Some people believe wealth is a zero-sum game, where there is a limited amount of wealth and some must lose in order for others to gain. As a result they are concerned primarily with issues of wealth distribution rather than wealth creation.

Others believe that wealth can be readily created. They feel that wealth is not a fixed amount to be distributed. To most of these people, organizing a society so as to optimize the growth of wealth is more important than distribution issues. Many of these people believe in some version of the trickle-down theory in which newly created wealth "trickles down" to all strata of society, thereby making the question of distribution mute.

One's attitude towards this issue affects the design of the social or economic system that one prefers.

The non-normative concept of wealth
Neoclassical economics tries to be non-normative for the most part, to be objective and free of value statements. If it is successful, then wealth would be defined in such a way that it would not be preconceived to be either positive or negative. This objective has not always been the case. In prior eras wealth was assumed to be a set of means of persuasion.

It was often seen as self-interested arguments by the powerful explaining why they should remain in power. In The Prince, Niccolo Machiavelli had commented in that earlier era on the prudent use of wealth, and the need to tolerate some cruelty and vice in the use of it, in order to maintain appearances of strength and power.

Jane Jacobs in the 1960s and 70s offered the observation that there were two different moral syndromes that were common attitudes to wealth and power, and that the one more associated with guardianship did in fact require a degree of ostentacious conspicuous consumption if only to impress others.

This logic is almost entirely absent from neoclassical economics, which in its extreme form argues for the abolition of any political economy apart from the service markets wherein favours may be bought and sold at will, including political ones - the so-called political choice theory popular in the U.S.A.. While it is entirely likely that such assumptions apply in the subcultures that dominate modern discourse on technical economics and especially macroeconomics, the less technical notions of wealth and power that are implied in the older theories of economics and ideas of wealth, still continue as daily facts of life.

Non financial wealth
The 21st century view is that many definitions of wealth can exist and continue to co-exist. Some people talk about measuring the more general concept of Measuring well-being. This is a difficult process but many believe it possible - human development theory being devoted to this. Although these alternative measures of wealth exist, they tend to be overshadowed by, and influenced by, the dominant money supply and banking system. For more on the modern notions of wealth and their interaction see the article on political economy.

The Creation of Wealth

Wealth is created through several means.
-Natural resources can be harvested and sold to those who want them.
-Material can be changed into something more valuable through proper application of labor and equipment.
-Better methods also create wealth by allowing faster creation of wealth.
-Ideas create wealth by allowing it to be created faster or with new methods.

For example, consider our early ancestors. Building a house from trees created something of greater value for the builder. Hunting and firewood created food and fed a growing family. Agriculture converted labor into more food and resources. Continuing use of resources and effort has allowed many descendants to own much more than that first house.

This is still true today. It is more obvious to those working with physical material than to a service worker or knowledge worker. A cubicle worker may not be aware in how many ways their work is creating something which is of more value to their employer than the amount that employer paid to produce it. This profit creates wealth for the owners of the organization. The process also provides income for employees, and suppliers, and it makes the continued existence of the organization possible.

The Limits to Wealth Creation

There is a debate in the economics literature, usually referred to as the limits to growth debate in which the ecological impact of growth and wealth creation is considered. Many of the wealth creating activities mentioned above (cutting down trees, hunting, farming) have an impact on the environment around us. Sometimes the impact is positive (for example, hunting when herd populations are high) and sometimes the impact is negative (for example, hunting when herd populations are low).

Most researchers feel that sustained environmental impacts can have an effect on the whole ecosystem. They claim that the accumulated impacts on the ecosystem put a theoretical limit on the amount of wealth that can be created. They draw on archeology to cite examples of cultures that they claim have disappeared because they grew beyond the ability of their ecosystems to support them.

Others are more optimistic. They claim that although localized environmental impacts may occur, large scale ecological effects are either minor (in terms of magnitude) or non-existent. They sometimes claim that if these global scale ecological effects exist, human ingenuity will always find ways of adapting to them. To them, there is no limit to the amount of growth or wealth that this planet will sustain.

Restricting the limits to the surface of Earth also restricts potential growth and the effects upon this planet.

The Distribution of wealth

Societies have different opinions about wealth distribution and of the obligations related to wealth, but from the era of the tribal society to the modern era, there have been means of moderating the acquisition and use of wealth.

In extremely ecologically rich areas such as those inhabited by the Haida in the Cascadia Pacific East Rim ecoregion, traditions like potlatch kept wealth relatively evenly distributed, requiring leaders to buy continued status and respect with giveaways of wealth to the poorer members of society. Such traditions make what are today often seen as government responsibilities into matters of personal honour.

In modern societies, the tradition of philanthropy exists. Large donations from funds created by wealthy individuals are highly visible, although small contributions by many people offer a wide variety of support within a society. The existence of organizations which survive on donations indicate that a society has some level of philanthropy.

In today’s societies much wealth distribution and redistribution is the result of government policies and programs. Government policies like the progressivity or regressivity of the tax system redistribute wealth to the poor or the rich respectively. Government programs like “disaster relief” transfer wealth to people that have suffered a loss due to natural disaster. Social security transfers wealth from the young to the old. Engaging in a war transfers wealth to certain sectors of society. Public education transfers wealth to families with children in these schools. Public road construction transfers wealth from people that do not use the roads to those people that do (and to those that build the roads). Some people resent having to contribute to some of these programs and disparagingly label them social engineering. The mere existence of government, transfers wealth from people in the private sector to people in the public sector. Contrariwise, the existence of a private sector transfers wealth from people in the public sector to people in the private sector

This phenomenon can be understood within a broad theory of political economy, where tradeoffs between means of protection, persuasion and production, and valuations of different styles of capital, are described. Simply put, if the rich do not at least once in a while give away, on their own free will, at least a small part of their richness to the poor, the poor would be much more likely to rebel against the rich.

The concepts of owning land and accumulating wealth in the form of land, were and are difficult to characterize in Enlightenment terms, bearing more resemblance to modern ideas of bioregionalism or ecological stewardship or natural capital. Ecological economics continues these traditions.
