As long as the US stays very rich and <4% of total global population, we will not run out of cheap foreign labor unless the rest of the world becomes very rich or die off en masse.

I don't believe we can rely on the idea of wealth and a never ending supply of cheap foreign lump of labor from anywhere in the world (it has not gone well for Europe, for example, and Sweden is paying migrants ~$34k to return to their country of origin). A majority of the US population supports deporting the existing undocumented immigrants in country, and limiting further immigration (do they understand this would stoke domestic service inflation? probably not). The wealth is immaterial if the electorate ties your hands politically. Demographic systems and political populism are running head long into capitalism. This story is a symptom of that.

(I am once again asking to think in systems)

This is not "running out of cheap labor".

This is tying your hands behind your back and not accepting it.

There's a difference.

The difference is the discussion, the outcome is what matters (imho). If something is technically possible, but impossible to achieve (for whatever reason), it is not truly possible.

There is, to my knowledge, no country that has solved its labor supply challenges with mass immigration in a sustainable manner. I am happy to be proven wrong if my understanding and model is inaccurate.

Qatar's population has been happy with their system for a while.

That's not Qatar citizens complaining.
