I don't think it's that Jerome Powell doesn't understand. Rather the central bank only has a few tools (interest rates/QE) to nudge the economy in the right direction. It takes real policy (Congress and the White House) to direct the investment to the more sustainable long-term investments

Here is the problem: if Powell is too successful with monetary tools, what incentive does it leave the policy side to do anything at all? He isn't powerless to force policy action by holding the line, but understandably he's more interested in keeping his job.
