The market will do it. Economic law destroyed the USSR. The USA is not more powerful than the market.
It took about 70 years and 70 million murders for economic law to destroy the Soviet Union (which isn’t as dead as we’d like to believe). That’s with a Cold War and outside pressure being applied by a free superpower and strong allies.
How long is it going to take economic law to save us with no USA to expedite the process? How many of us get to die while we sit around waiting for it to run its course?
