Exactly. This world is one giant socio-economic lab. As long as there are borders and each economy is effectively contained, supported, and enforced, those economies can survive and even prosper given the right leadership and participation.
Drill a hole in one container and the solution spills out. The problem is you can't just drill a hole in one container without damaging the container next to it and compromising the solution inside it. But that is exactly what the Clinton admin and congress did with Nafta and Mexico (and with China though no one had any idea China was part of and purchasing/ influencing that deal).
It seems great that suddenly there are cheap goods available to people used to paying more, but the effects over time are always the same. Dilution and compromise of solutions. Lowering of wages compared to established, currency related costs. You either plug the hole and fix the solution, or you just add more of the same ingredients to hide the dilution (print more money). The end result is the solution gets out if balance, stagnates, and either the ingredients precipitate out of solution (no movement/heat) or the solution thickens to the point of being useless.
There's a reason there must be a balance in systems. There's a reason systems decay once that balance is altered. We're seeing the results of the successful marketing (propaganda) of "new" (old) ideas that failed in the past, marketed by people that know how to and are positioned or waiting to profit off of those failures, marketed for and to people that increasingly are propagandized not to care how anything affects anyone else.
