America's deeply unequal political system WILL NOT ever get us better equality. It's *incidental*, a symptom of the political reality that discouraging cars would be done in a way that exacerbates inequality.
Almost any policy can be done in ways that exacerbate inequality. And a more equitable political system would be needed in order to have more equitable policies.
There's nothing specific to cars about this stuff. So, there's no point in focusing on discouraging cars as inherently part of this trend. Gentrification is a real issue. But don't blame yoga for gentrification just because yoga studios are in gentrified areas. Policies that encourage healthy tree canopy also exacerbate inequality because richer areas can hire urban foresters and so on. I mean, every single worthwhile thing you can think of exacerbates inequality if the policies are set up to make the worthwhile thing go along with already-wealthier places. None of the worthwhile things are themselves the cause of inequality.
