Nations that will provide a better life for working adults in 15-25 years than the USA would

A lot of the discussion I see about moving out of the USA is geared to moving to a place where one's $ goes further than the local currency or where housing, healthcare, costs, etc. are affordable and good quality. Noble goals all of them.

Assuming, however, one's priority was rather to set up one's young children up to be educated and connected in a nation whose labor market and laborers' quality of life is predicted to be stronger or as strong as the US labor market - which nations would be attractive targets for immigration?

I recognize it is difficult for anyone predict what the value of labor may look like for workers, 15-25 years, but if you had to shake your Magic 8 ball and take a guess, what nation's names might rise in blue to the surface?
