Compare and contrast socialism, communism, and capitalism. you may use a graphic organizer, such as a t-chart, or a paragraph format. cite each source. at the bottom of your page, provide one or two sentences to explain how two of your sources is reputable. also, include the full citation for those two sources.

I'll simply give you some general thoughts in paragraph form.  You'll need to do your own research for citing sources.
Socialism:  Members of a society contribute to each other's needs and provide help to one another.  The earliest socialist efforts were somewhat small-sized communities or groups that lived and worked together cooperatively, such as the factory town reformed by Robert Owen at New Lanark, Scotland.  In the modern world, socialism generally means national measures through taxes and government programs so that those with more resources in terms of private property provide aid to those less well off.
Communism:  Communism was called "scientific socialism" by its founders, Karl Marx and Friedrich Engels.  The "science" of it believed it was the inevitable path of economic history.  It expands the socialist project so that all members of a society have all in common and everything equal.  There is no private property; all is intended to operate communally.
Capitalism:  Capitalism is built around the pursuit and protection of one's private property.  In a purely capitalistic system, there would be no income redistribution by taxing those who succeed at business in order to give aid to those who aren't as successful.  
Most modern governments incorporate elements from more than one system.  China is governed as a communist nation but pursues many capitalistic endeavors.  The United States runs on capitalism, but there are many government-run social programs (a form of socialism) that provide aid to those in need.
