I wouldn't call it "obvious" that someone would accept another's opinion without any info to back it up and then extol it, though it's very interesting to me that you did.
What data did your friend use to come to that conclusion? Would you be willing to share so we can come to our own conclusions based on the evidence presented?
edit: or would you prefer "that's what a free market does"? Either way, this is a remarkably incendiary, and frankly absurd, attempt to recast voting with one's wallet as "dictatorship".
