No, I think you are right on. As someone else pointed out, if our economy continues at a growth rate of only 2%, and inflation remains at 2%, then the Fed will keep interest rates <2.5%. This creates a situation that all the banks, hedge funds, & wealthy can borrow cheap money and the only decent returns are in equity markets. Keeps the markets inflating. Doesn't do much for the middle/working class with the exception of 401k accounts.
This and the Trump tax cut factored right into it. Many corporations took their tax cut, and started buying back their own stock. Thereby inflating the prices of that stock even higher. Good for the CEO types who receives hefty bonus checks based on the price of the stock.
The problem is the they corporations are not expanding and producing more, they are not hiring more workers or increasing their wages.
84% of all stocks are owned by the wealthiest 10% of Americans, so the rest of us are not getting any benefit except in your 401K. I would say that since many of us, cannot pull that money out at any time without paying a huge penalty, for most of us, its current price really does not help us out a whole lot.
