Japs are investing smart. They are pouring billions of dollars into cybernetics to ensure that their nation does not need immigrants and to compensate for aging of their population.

Cybernetics are not even needed, if that.  The only reason my country has a construction boom is because we constantly have to build Condominiums for the arriving population.  Technologies have made most of the workforce redundant and various bubbles have otherwise resulted in unnecessary jobs for wide segments of the population.
