How Communism Works"

In a perfect world, everyone would have food and shelter, and a true utopian society would be devoid of sexism, racism and other forms of oppression. But for most of the world's population, this perfect society just isn't possible. Communism is one proposed solution to these problems. Most people know what communism is at its most basic level. Simply put, communism is the idea that everyone in a given society receives equal shares of the benefits derived from labor. According to the philosopher Frederick Engels' "Principles of Communism," the plan for ultimate financial and social equality is built on the principle that the system should spread around the world until all countries are on board [source: Engels]. Who are communists, and why do non-communist cultures consider them radical?
