The risk of putting rates too low is that you could drive up inflation or the economy overheats and creates some imbalance somewhere that has to be dealt with.
The real effects of keeping rates too high is that the country can’t borrow as cheap and so our debt service payments remain high. That directly affects the Federal Current Deficit, impacting future debt levels.
I’m with Trump. Lower those interest rates, keep the economy humming, make it easy to reinvest here in the US. Give Trump room to negotiate trade wars.
A reasonable argument. But Trump still should not refer to the Chairman of the Fed as the “enemy” (and I do not mean to imply that you agree with this characterization).
