All of the policies you want only get brought to vote when it is impossible for it to pass

It might be now, because nothing is possible anymore, but before current round of shitsow, amazing amount of smaller bills and propositions were passed, they weren't flashy ones (and that's why there were passed, under the radar), but it helped immense amount of people. Everything big, like medicare for all, requires so much more work, it was never possible to do in that short periods of time US government wasn't overwhelmed by reactionaries.
But that's all that people can actually achieve, for now.
