I think you’ve just reinforced my point that the wage problem is partly due to “the decades-long failure of anti-trust enforcement resulting in highly concentrated industries in which there is little actual competition”. Walmart is able to offer low prices because it is so big that it can literally dictate what if will pay (often even below cost) to suppliers. Yes, maybe a smaller degree of business concentration would raise prices, but it should also lift wages. And even if we didn’t break up the monopolies, the idea behind globalization was that, within each country, there would be winners and losers but overall the world would be richer. That has turned out to be the case. But instead of taxing the within-country beneficiaries of globalization and reinvesting it in the losers, we simply let the winners keep it all.
