The Fed can do only three things: (1) raise or lower the short term interest rates it charges financial institutions when they borrow from the Fed, (2) raise or lower the short term interest rates it pays financial institutions when they park money with the Fed, and (3) buy and sell US treasury and mortgage agency bonds in the open market. And the Fed does these things to ensure financial and monetary stability.
The OP strikes me as an ideologically driven piece that takes a few quotes from Powell completely out of context and manipulates them to fit a narrative that makes no sense whatsoever given what the Fed is (a central bank) and what it can do (change some rates it pays/charges and trade some government and agency bonds).
To the mods: consider removing the OP. I doubt it fits the HN guidelines.
