I agree.
My take on it is that with "Reaganomics" we went from tax-and-spend to borrow-and-spend. That has resulted in ongoing asset inflation that, along with continued increases in spending by the federal government for health and the military, has created a vortex of hyper-prosperity among the rich. Some of the money of that vortex dribbles onto the people in the rest of the economy. In short, Reaganomics is working as designed.
There is, by the way, a better option than taxing the rich: "For Crying Out Loud, ACCEPT That A SOLUTION Actually EXISTS" (a "3 min read"--including options for further reading--here in Medium). This idea needs advocates.
