Rent control, the landlord, monopoly, and exploitation: challenges put forward by anti-capitalist advocates and occasionally by supporters of a "free market". Walter Block, one of the most well-known Libertarians of our age, has studied and methodically attacked these ideas, first in his doctoral dissertation, then a few years later in the book "Rent Control; Myths & Realities" in conjunction with economists like Edgar Olsen, Friedrich von Hayek, Milton Friedman, and several others, as well as in essays throughout his long, prosperous career. Block is one of the most notable students and friends of the great Murray Rothbard, who has emulated his drive as a teacher and educator, as well as a continuation of his genius throughout dedicating his life to promoting economic and individual liberty.
