Earlier quoted context omitted.
Does every retired boomer living quite well off their 401K retirement plan represent a member of 'the investor class'? How many would be willing to accept a cutback in dividend payouts if it meant corporations would instead invest that money in rebuilding manufacturing in the United States?
The investor class being those that have significant political influence. I sure don't recall any large boomer political movements demanding more offshoring. In fact, a politician promising the exact opposite was quite popular. But because they reap some minor, incidental payoff from a policy they did not choose, you're going to claim that means they were in favor of it??
People want money, in my experience. Cut their money flow and they get upset. Any effort to rebuild manufacturing in the USA will require corporations - major blue-chip outfits that pension funds invest heavily in - to spend billions of dollars building new factories and hiring employees at wages a good deal higher than what it costs in mainland China, Indonesia, Mexico, etc. This will cut dividend payouts to pension funds. Boomers riding their 401Ks off into the cruise ship sunset will get upset about that I imagine.
