Arguably the greatest economist of the last century, Milton Friedman was an active contributor to Reason magazine. Doherty has collated a series of some Friedman's best insights from those contributions and they have been posted here.
These themes are discussed further in a contemporary setting on two websites that are new to me: QandO and the Liberty Papers. Both offer answers that bridge the work of Friedman with the political insights and philosophy of Jefferson et al. on how a civil society can retain its freedom but not fall victim to the vested interests so constraining Latin America.
