>which that those wage gains didn’t make up for the 40 years of stagnation preceding it.
It stagnated in 2008-2016 but they still voted for obama, but when it finally started rising in 2016 they voted for trump?
It wasn't really rising in 2016. The flat wage growth lasted past 2020, with a relatively recent blip, but it has not meaningfully risen to outpace the stagnation that existed for decades.
If wages increased with productivity increases we'd be in better shape overall as a society, but here we are.
