Yeah, that's pretty bonkers, complaining that the Fed didn't keep interest rates low enough and was too shy about engaging in more QE. That could only be written by someone who hasn't the slightest concern about debt loads or becoming a centrally planned economy.
The fed is our problem period. A monkey with a dart board could do a better job. Their only mandate should be them acting as a lender of last resort during a liquidity crisis. That is it, the other mandates can be accomplished by a free market, which also doesn't unfortunately exist. We really just have a corrupt crony capitalist system. How would the economy be doing if suddenly every single citizen cut their spending by $3000 a year. That is how much debt is being pumped into the economy per year by the govt. enabled by the fed.
