I like the way Joseph Sobran puts it in the Liberty and Economics bio documentary of Mises:
“There’s a three word lexicon that explains the tax economy: ‘need, greed, and compassion.’ ‘Need’ now means wanting someone else’s money, ‘greed’ means wanting to keep your own, and ‘compassion’ is the sentiment of the politician who wants to arrange the transfer.”
As Block says in his essay: “in making the case against socialism, Hayek was led into making all sort of compromises with what otherwise appeared to be his own philosophical perspective – so much so, that if a system was erected on the basis of them, it would not differ too sharply from what this author explicitly opposed.”
