My two cents:
I've read his book, but never seen the show.
Arrogant or not, he's exactly correct when he says the vast majority of rich people in this country got that way by working like dogs, something too few people nowadays are willing to acknowledge. As a society we romanticize the poor and villify the rich in an almost kneejerk fashion, when the truth is that most people end up in their financial situation as a result of choices, good or bad, and not luck.
Whether the pursuit of material wealth is a worthy goal to make the centerpiece of one's life is an entirely separate argument, more in the realm of faith and philosophy than yahoo! finance.
IMO, Kiyosaki is full of crap and the only reason he has any money is from selling his get rich quick books. His books' "advice" is exceedingly poor and could land someone in jail.
