When the house starts to fall, you can either add a support and pray it keeps going, or rebuild it all.

And the more you take the first option, the more it takes you to just keep the thing upright. At some point, a sane person says “the time has come” and rebuilds the house.

Same here. Rebuilding an entire economic system, especially when the most powerful people on Earth try to preserve it, is no easy feat - but it is a more permanent solution.
