No less a liberal than Frank Zappa said it best--Marxism will never, ever happen in America because people like to buy stuff. :)
In some ways Zappa was a lot less liberal than you'd think, he was all over the place and changed on several things as he got older. But as a boss he was a fascist against alcohol and drugs. By the early '80's he had a policy of firing anyone that got high or drank on or off the job! - per my friend, Zappa's comptroller for tours.
