Competition in biology, ecology, and sociology, is a contest between organisms, animals, individuals, groups, etc., for territory, a niche, or a location of resources, for resources and goods, for prestige, recognition, awards, mates, or group or social status, for leadership; it is the opposite of cooperation.[1][2] It arises whenever at least two parties strive for a goal which cannot be shared or which is desired individually but not in sharing and cooperation. Competition occurs naturally between living organisms which co-exist in the same environment.[3] For example, animals compete over water supplies, food, mates, and other biological resources. Humans compete usually for food and mates, though when these needs are met deep rivalries often arise over the pursuit of wealth, prestige, and fame. Competition is also a major tenet in market economy and business is often associated with competition as most companies are in competition with at least one other firm over the same group of customers, and also competition inside a company is usually stimulated for meeting and reaching higher quality of services or products that the company produce or develop. A competition or trade promotion lottery, is also the equivalent of sweepstakes in some countries. Wealth is the abundance of valuable resources or material possessions. The word wealth is derived from the old English weal, which is from an Indo-European word stem.[1] An individual, community, region or country that possesses an abundance of such possessions or resources is known as wealthy. The concept of wealth is of significance in all areas of economics, and clearly so for growth economics and development economics yet the meaning of wealth is context-dependent. At the most general level, economists may define wealth as "anything of value" which captures both the subjective nature of the idea and the idea that it is not a fixed or static concept. Various definitions and concepts of wealth have been asserted by various individuals and in different contexts.

2] Defining wealth can be a normative process with various ethical implications, since often wealth maximization is seen as a goal or is thought to be a normative principle of its own.[3][4] The United Nations definition of inclusive wealth is a monetary measure which includes the sum of natural, human and physical assets.[5][6] Natural capital includes land, forests, fossil fuels, and minerals. Human capital is the population's education and skills. Physical (or "manufactured") capital includes such things as machinery, buildings, and infrastructure. For definitions of "wealth," see also The Wealth of Nations and Max Weber, The Protestant Ethic and the Spirit of Capitalism. Adam Smith, in his seminal work The Wealth of Nations, described wealth as "the annual produce of the land and labour of the society". This "produce" is, at its simplest, that which satisfies human needs and wants of utility. In popular usage, wealth can be described as an abundance of items of economic value, or the state of controlling or possessing such items, usually in the form of money, real estate and personal property. An individual who is considered wealthy, affluent, or rich is someone who has accumulated substantial wealth relative to others in their society or reference group. In economics, net wealth refers to the value of assets owned minus the value of liabilities owed at a point in time.[citation needed] Wealth can be categorized into three principal categories: personal property, including homes or automobiles; monetary savings, such as the accumulation of past income; and the capital wealth of income producing assets, including real estate, stocks, bonds, and businesses.[citation needed] All these delineations make wealth an especially important part of social stratification. Wealth provides a type of social safety net of protection against an unforeseen decline in one’s living standard in the event of job loss or other emergency and can be transformed into home ownership, business ownership, or even a college education.
