My point is that the expertise drain is going to hit those other countries too, within our work-lives given the demographics of China, Korea and Japan. The same thing is happening over there to even worse degrees, youth unemployment is already massive problem in east asia and when all those trained workspeople and engineers leave the work force in ~30 years.

Sure then that expertise could migrate to other countries, possibly some in Africa. But the demographics slow down is probably already going to afflict those countries before the expertise leaves east asia in the first place.

I truly believe that within 40 years we are going to have a massive infrastructure maintenance problem, where the world will run dry of trained professionals to maintain everything that is already built. And, like I mentioned above, the wealth inequality will reduce because the owners of capital will need to pay premium rates for qualified workforce (think how cobol is today).
