Stagnant real wage growth, sure. Stagnant, so not significantly worse.
Health care? US-specific - how do you explain the massive growth of fascism in countries with reasonably well-functioning health care systems and universal health care?
Union membership? US-specific - how do you explain the massive growth of fascism in countries with 50%+ union membership rates, massively more politically influential unions and widespread collective wage bargaining?
Minimum wage? US-specific - how do you explain the massive growth of fascism in countries where even the minimum income (i.e., for the unemployed) is far above the US federal minimum wage?
Inequality? A global problem, to be sure. But how do you explain the massive growth of fascism even in countries with dramatically lower inequality, poverty and crime, and with universal access to health care and top-tier education? In fact, some of these countries are among the most egalitarian in human history since the advent of agriculture thousands of years ago.
Why did fascism emerge now as suddenly so much more popular? Could it be, perhaps, not something economic at all, but something else? Like maybe people being bombarded with fascist propaganda 24/7?
