Karl marx and communism

Karl Marx thought communism would ruin society.  His prediction of society being ruined was correct.  He thought that society would be overrun by business, and that thats all people would think about.  And this is true, because everyone who has a business is just obsessed with work.  All they due is work, like one of the comics we read everyone was a computer head, the computer ran there life.  And this is now ruining society just like he predicted.
