Japan is not making any gains on productivity because, as I said, it has an aging workforce. Older workers are less productive than younger workers. Which is the same demographic bottleneck the USA is sliding into. We see in Japan the possible future for the USA.
Let me restate the MAGA belief in more concrete numbers: MAGAs believe we can increase the sector of the American economy devoted to manufacturing physical things from the 10-15% it represents now, to the about 30% it represented in the 1960s.
You yourself say that the increase will come generally from productivity, not from increases in population. So, what you are saying is that the aging, decreasing American workforce, is going to double or triple productivity.
My question is, why isn’t American industry doing it now? Where I live there isn’t enough workers to staff factories now. If there was a magic fix for that it would have been done.
Not trying to change your belief that it can be done. I just don’t see it happening. Because I see the demographics at work in other wealthy countries, with hard-working populations healthier then our own.
