well j_b...it might be that there are some idealists who think that the concept of a freemarket is bullet proof...these people aren't out to "make a buck"...they are true believers (just like some idealists believe that the concept of communism can work). i don't think either people are "evil" or out to crush the will of the people or make a buck at the peoples expense. they just believe in that particular system.
then you have the actual implementers of either system. there are a lot of good people, but in the end both system have boiled up some pretty bad apples. it seems that ugliness has ensued in either case...though one could argue that one system is less ugly than the other.
