There's nothing an actively-aiming-to-harm-others-for-their-own-gain person loves more than someone else deciding to stop trying because it's 'rigged.' The assholes are internally motivated to continue to being assholes. That takes continual active resistance.

Health access, for instance, improved as a result of one set of votes. Lifetime maxes are gone. There is improved access to non-employee plans.

It didn't stop inflation of health plan costs or medical treatment in general. One might think that means its worth voting for people pledging to make further large-scale changes to address those things.

And meanwhile, the assholes have been campaigning on the opposite for more than a decade: try to make the access worse again by trying rhetorical tricks to say that the one caused vs failed to fix the other. That'll let some rich people get even richer.

That's a real difference for many millions of people.

Neither party is perfect. Welcome to adulthood. Shitty compromises are generally all you get.

By all means, work on structural things to encourage more parties to exist and flourish.

Just also pay attention to the active battles.
