OK VK if you want to discount the learned Thomas Sowell as a mere "conservative columnist", but you really should learn a little more about him before you do.
I'm guessing Mr. Sowell has written more books on economics that you have and might even have a more extensive education and life in educational settings than you have, although I could be wrong because I only know of the vast education and brilliant writings of Mr. Sowell and not really much about you, so forgive me if I'm mistaken.
