“Don’t let perfection be the enemy of progress” or something like that.
Brings back memories to when Obamacare was announced. Did it go far enough? Hell no. It was a step in the right direction and it was still derided. Those who are ripping down the system brick by brick have a singular vision and understand it's a series of steps to get to their dystopian hellscape. Why are those primary on the left unwilling to accept anything that isn't a fully realized picture of their ideal society?
In fact I'd argue a large part of why the system is falling apart is those who want to see it improved are unwilling to do those small incremental changes for good.
