“Scratch the surface of an endemic problem — famine, illness, poverty — and you invariably find a politician at the source.” — Simon Carr, in his review of The Mystery of Capital by Hernando de Soto
So often “Libertarianism” is the flimsiet cover for being a pervert — my experience from NY to Seattle to L.A to Miami.
