Prior to the last 3 recessions the fed interest rate was somewhere in the 5.25 to 7.75% range. The fed was able to drop the interest rate 4-5% to stimulate the economy. Right now the interest rate is 2.5% - it's pumping trillions of dollars worth of free money to prop up the economy. If Trump has his way it will go even lower. So what happens when the inevitable occurs and corporations and individuals can't carry anymore debt and/or start defaulting and the slowdown begins - the fed has no leverage to stimulate the economy. This isn't a partisan hit job - this has been going on way before Trump. In fact, Trump himself correctly called this a "false economy" when he was running for president. We're literally in uncharted territory economically.
