What is a Capitalist nation?

The term capitalist is not referred to the type of nation or nation's government, it refers to it's economy. In this economy there are three classes for example USA, of which has an upper class/workers class/lower class. Unlike a communist government that everyone has the same everything. The government can tell you what you can and can't have; basically there is only one class and no one has any more money than anyone else. China as we know is a major Communist nation that survived the cold war unlike the USSR or Soviet Union. China will make you take a test and depending upon the score you get on this test is where you will be given a list of jobs you can have and then they tell you. This is why America is a land of opportunity
