In contrast, recent trends do differ by education group. Until 2012, Americans with the most formal education (Bachelor+) were the most pro-business. By 2024, they became the most pro-union. On the other hand, Americans with the least formal education (less than high school) were historically among the most pro-union but recently became the least pro-union. High school graduates, some college, and bachelor-plus all expressed record-high pro-union sentiment in 2024. Even those without a high school degree remained near their record high.
Yeah, I suspect that is the Fox News effect. I think their propaganda works best on the the under-educated. Forty years of anti-union propaganda has manage to push blue-collar workers, who get the most help from unions, into anti-union territory. It never ceases to amaze me how people can be tricked into voting against their own interests.
