Milton Friedman on greed:
Did you know Friedman helped invent the United States payroll withholding tax system? It’s a little like how Alfred Nobel invented dynamite, then invented that whole prize thing as a sort of apology to humanity.
Unlike Nobel, he made no apologies for his work, but did state in an interview with Reason magazine that he wished “there were some way of abolishing withholding now.”
