This is what blows my mind about the "Democrats are center-right ghouls" (accurate) -> "Let's stop voting for Democrats that'll fix it" conclusion. The first part is accurate, the second is a terrible strategy to arrive at to fix it.
The whole of Washington is profoundly corrupt. Anything that comes within its AoE radius starts to suffer this overwhelming pressure (financial, narrative-manipulation, violent, social, whatever else) to become neoliberal. Sure, that includes Democrats too, a lot of them are the fuckin' worst. Fixing it and getting humanity back into the politics is an urgent problem. But just holding your nose and walking away, hoping that it'll then start arriving at reforms on its own, instead of trying to improve things (through whatever means), is pretty much guaranteed to failure I think.
