Hmm, outsource jobs to Communists, let them see what it like to earn money in a capitalist's society and what it gets you (after all, the thousands of gadgets on the assembly line are coming here, not to their local collective). Before long, the smart ones start saying, "why can't we have this?" Then the brave ones try to make things better, guys like Lech Walesa and the Chinese guy who stood in front of a tank, and, hopefully win. It kind of sounds a little like history repeating itself doesn't it?
I guess when Communists have done the right thing and let people choose what type of government they wanted to live under, they (Communists) have consistantly lost. It is only when they speak with the tank, secret police and quash the opposition's voice that we find them as winners.
