I do think catering to nimbys was the democrat’s original sin in some respects. Housing unaffordability makes everything else worse and blue areas are especially bad.
Especially in CA where the Reagan Tax Revolt lives on in CA Prop 13, where boomers sitting on $2m+ properties that they bought in 1978 for $40k pay <$1k/year in prop taxes while their new neighbors pay $40k/yr in addition to their 8% mortgage while the boomers vote down any new housing developments or zoning changes.
