The sad thing is what they really miss is reasonable restrictions on industry and capitalism, a viable chance to support a family on a single full-time salary, and upward mobility, but rather than getting mad at the greedy capitalist assholes that have stolen these things from them, instead they let these exact same greedy assholes trick them into thinking that minorities and disempowered peoples are somehow the ones stifling progress.
The yearning for better days isn't inherently wrong, it's the conclusions they draw where they go astray.
