That's so many assumptions you might as well put on a robe and special hat and become a fortune teller. The effective erosion itself is a policy choice, there is this thing called 'minimum wage' which you can use to make sure that there is more than just 'warm bodies' as the lowest common denominator in job requirements, and as a result everything above that has to be 'upgraded' to a higher standard as well, otherwise people aren't willing to do the work (just like is happening now). The examples are all around you. There is no onshoring of talent or natural resources since they are not 'constructed' the same way and importing those are against the current ideas/fears of immigration and relying on third parties for goods. In other words: globalisation isn't a choice, it's a side-effect from the needs of humanity. Reverting to a more primitive state that decreases those needs could be a path, but I doubt anyone would choose that willingly. Besides those things, there is this concept of ideals or principles which are almost as important and it doesn't require any extreme form of meddling either. If people really care about something (say, the well-being of other humans and therefore not really being happy with an authoritarian regime somewhere) then that can be incentive enough. And if it isn't then some protectionism won't be enough either.
