the Chinese like to say practice is sole criterion for truth. the effectiveness of a system is the result it delivers, not some abstract theory. however good a system sounds in a classroom is irrelevant if it doesn't work in reality. of course, ideologues will never understand this. that's good for their opponents who do understand it. ideologues are the easiest adversaries to defeat.
