There is no undoing some of the damage. The dollar will never be a reserve currency again. Petroleum-dollar recycling is dead. Our trade position is unrecoverable and millions will die because of it.

So to minimize the damage longer term; deploy ranked choice or STAR voting across the country. Strip as much power from the executive branch as possible, allow the post office to provide banking services to everyone and authorize them to issue home loans to everyone at 2x their annual income at Federal bond rates. Then authorize Medicaid part D to be available to all citizens at cost (thus providing a single payer healthcare option).

Change corporate tax into a graduated revenue tax model, which would make too big to fail to become too unprofitable to survive; (higher revenue => more taxes because you can’t hide revenue but you can game profits) thus cutting the tax burden on small businesses and giving Wall Street an economic incentives to rip massive corporations into spreads.

Then there are a fuck ton of targeted policies that will have to be deployed to help repair the economy and rebuild industries in the country.
