Let us not worry about "the whole economy". Yes, we know there is massive Executive overreach with tariffs and immigration. Yes, we know Congress is deadlocked to the point of being worse than useless. Yes, the SCOTUS also has its own problems with a majority of the public no longer having any faith in the judiciary. Lets start with things the FEDeral Reserve can fix, right here, right now.

Narrow banking now.

This is something the Federal Reserve can actually fix. Give every single US person (I am not a lawyer and I can't define what counts as a US person) a fee-free bank account with the Federal Reserve. Cut out the middle men of commercial banks. I think that alone will go a long way to drive down business costs.
