(Can you explain this please? Because the cost of post war strategy, bretton woods, and maintaining the rules-based order, world free trade, and constraining aggressor countries, has largely come at the expense of the american laboring, working, and middle classes, through the increase in world manufacturing competition and the export of their jobs, at their expense, while the upper middle and upper classes have captured enormous gains. So you might claim the upper classes have but… I don’t understand how the middle and lower classes have.)
