I can't count the number of such situations I've found myself in over the past decade or so, and I wish I had this pearl from William Norman Grigg (Pro Libertate), published today on LRC:
Obama is a reasonably bright fellow. Somebody he respects – assuming there is any great enough to command his attention and rebuke his errors – needs to ask him this question, and compel him to answer:
"If the key to prosperity is a centrally planned economy fueled by fiat currency, why isn’t Zimbabwe the wealthiest nation in history?"
Yes, indeed, why not?
