Most of the things you mention, poor enforcement of tax havens, immigration policy, low taxes on capital, massive military spending, coincided with the development of globalism or were a reaction to it.
But regardless I disagree with your thesis, as I hardly see globalism as something that's detrimental to America as a whole. That may be the mainstream narrative but it's largely inaccurate. The thing about capitalism is that it goes throw booms/busts and it evolves. This is just another phase and we've all been pretending we're in control but the reality of the situation has become apparent recently.
So the dichotomy between historical fluke and market trends doesn't really exist. Historical flukes are market trends.
