Libertarians have lost another great man this year. (Harry Browne passed on months ago) Milton Friedman was one of those guys who made so much sense that every president had him to the White House to sing his praises then turned out to be too chicken to follow his advice. Friedman is known for coining the phrase There's no such thing as a free lunch.
In tribute to Friedman I'll offer one of my favorites of his quotes:
"Nobody spends somebody else's money as carefully as he spends his own. Nobody uses somebody else's resources as carefully as he uses his own. So if you want efficiency and effectiveness, if you want knowledge to be properly utilized, you have to do it through the means of private property."
