The thing is...unbridled pure captialism...a truly free market is just as much of a pipe dream as the communist Utopia. George Will said it best...a good Capitalist system needs to be watched over. Monopoly control, prohobitions against Insider Trading and such.
Who's going to be the one to "watch over" the capitalist system? The government? Saying that capitalist corporations are vulnerable to corruption and hunger for power while governments are not is not only hypocritical, but completely false. Just look at history. Some capitalists have certainly done bad things, but governments have done far worse. Every genocide in history was perpretrated by governments, not corporations. Capitalism is not perfect, but it's the best system that's available.
Pure free-market capitalism is like leaving the henhouse unguarded. Having the government "watch over" markets is like having the fox "watch over" the henhouse.
Thats not a problem with the system. Its a problem with the humans participating in the system. If we all had a moral code that stated stealing was wrong, unbridled capitalism could be fully implemented. Unfortunately, the problems are not just with humans working inside the companies. The problem also exists within those who purchase products from the companies. It seems that the prevailing moral code now in America is to try to get as much as you can from a company when you make a purchase. The human problem exists on both sides of the transaction. If our people had better moral codes of conduct our ecomony and therefore our future would be growing much faster. And we probably would not be sitting back wondering how many people were murdered in Los Angeles today.
