What would happen if there was a worldwide communist revolution?

As we all know, after the end of the Cold War, capitalism won.<br><br>However, I was wondering what would happen if communism won. What would happen..<br><br>For example, if all wealthy nations today became communist, would all rich people have everything they owned taken away? Would they be put in a work camp if it was deemed that they were using their wealth to exploit others?<br><br>What would happen to the global economy? Would international trade cease to exist? Would everyone have a standard job allocated to them?<br><br>Let me know your thoughts. Every little bit helps the discussion!
