>how do we get the economy working again

Just like we always have: a world war, and then the economy works amazing for the ones left on top of the rubble pile where they get unionized high wage jobs and amazing retirements at an early age for a few decades, while everyone else will be left toiling away to make stuff for cheap in sweatshops in exchange for currency from the victors who control the global economy and trade routes.

The next time the monopoly board gets flipped will only be a variation of this, but not a complete framework rewrite.
