The following excerpts, as to the definitions of each, were taken from Wikepedia. For a more in depth meaning as to each definition, visit Wikepedia. I highly recommend a visit; it will be enlightening. Contrary to what so many have claimed about this one or that one being a form of government, none are touted as such, instead they represent a theory that can be applied to any society, even a democracy such as ours. Pay particular attention to the last one. Capitalism is an economic and social system in which capital and land, the non-labor factors of production (also known as the means of production), are privately owned; labor, goods and resources are traded in markets; and profit, after taxes, is distributed to the owners or invested in technologies and industries. Also see rise of financial capitalism, which controls all other forms of capitalism. Socialism refers to the various theories of economic organization which advocate either public or direct worker ownership and administration of the means of production and allocation of resources. A more comprehensive definition of socialism is an economic system that directly maximizes use-values as opposed to exchange-values and has transcended commodity production and wage labor, along with a corresponding set of social and economic relations, including the organization of economic institutions and method of resource allocation; often implying a method of compensation based on individual merit, the amount of labor expended or individual contribution.Progressivism is a political attitude favoring or advocating changes or reform. Progressivism is often viewed in opposition to conservative or reactionary ideologies. The Progressive Movement began in cities with settlement workers and reformers who were interested in helping those facing harsh conditions at home and at work. The reformers spoke out about the need for laws regulating tenement housing and child labor. They also called for better working conditions for women. Egalitarianism (derived from the French word égal, meaning "equal") has two distinct definitions in modern English. It is defined either as a political doctrine that holds that all people should be treated as equals and have the same political, economic, social, and civil rights or as a social philosophy advocating the removal of economic inequalities among people.
