There are countless comments and discussions on this board about how:
1) interest rates should be zero,
2) interest rates being non-zero create a misallocation of capital where there is a return on an investment without any ingenuity or creation behind
3) Banks are too risk averse to lending and their risk averse behavior is due to the risk free rate they enjoy when they park money at the Fed and when they buy T-bills
No matter how little ingenuity or creation is required to keep afloat a zombie company or a dubious startup, for sure it's a notch higher than what happens when that money is parked at the Fed or invested in t-bills...
