“I don’t think the government is so much deliberately driving up stock prices”
They are deliberately printing money and holding down interest rates. The 47% low information voter usually equates the economy with the stock market, so if its up they think the economy is good.
Judging from the history of every demonrat controlled city/state there will be no efforts on their part to bring this under control.
The government in this case is the Federal Reserve, putatively non-partisan. The Federal Reserve, in order to “help” the economy is buying Treasuries at low rates to keep government borrowing cheap. This is very little different than just printing money. This policy, pursued long and vigorously enough, will kill the dollar.
