What a bunch of nonsense.
For seven years now we’ve been told the US is in a recovery. However, if this were the case, the Fed would have started raising rates years ago (likely in 2012). No other recovery on record saw the Fed maintaining ZIRP for so long.
There is simply no factually credible argument for why rates should be ZIRP if the economy is expanding. You cannot have claims of a “recovery” or expansion while ZIRP is in place. ZIRP is meant to be an emergency policy meant to pull the economy out of a severe recession, NOT a long-term program.
