And probably it is also the only thing that China wants so that can try to corner the market. But if they move half of the production oversea then they probably will become less appetible for China since they cannot really control the production.
Not that they must do it, just a consideration.
It is not a shame, it is expected but not always possible.
It is not a problem of productivity but a problem of how many years you work before retiring and how many year you live after you retire (with the obvious exceptions).
I agree that the increase in productivity should generate an higher pay for the worker but that is sustainable up until a certain point, you cannot expect to work for 20 years then to live 40 or more years in retirement with the same standard of living since what you get while retired is what you accumulate while working, even with a higher productivity.
