As you've mentioned, I don't think deciding what industries we should focus on/invest in is within the purview of the Fed.
Btw, I don’t think there’s a simple solution here, and banks aren’t necessarily to blame here. They’re merely reacting to the incentive structure. To solve the problem we need deep structural changes in how we view economics. I’m one of those people that like aspects of both MMT and crypto assets.
Addition: since my comment is a bit too light on practical solutions, I think we should have a decentralized way in which local communities can direct money creation towards productive long term projects that help that community. And the same can be done at the federal level for very big projects (rockets, dams, infrastructure etc)
What are they currently doing wrong, in your view, and what should they be doing better?
Lots of fed hate on HN nowadays. I personally think that they are doing a so-much better job than '08 and am happy that academic economists seem to at least be learning a few lessons.
