Late Stage Capitalism

How much time? Ideally none. But the real world isn't idealistic, and breaking more shit because you can't have what you want right now is what petulant children do.

I'm not defending the establishment Dems' inaction, but I am cautioning against setting unrealistic expectations. Even if you vote out all the republicans and replace all the democrats with progressives, it will still take time to fix things.

And people's ignorance about this fact is a key part of the republican strategy that keeps getting them reelected every other election cycle. They always break shit on their way out, leaving a mess for their successors to clean up, and they blame it all on the democrats in office after them.

So promoting this idea that you can fix everything overnight is only helping the republicans.

Incrementalism is a tool of fascism to prevent progress.

No, incrementalism is a necessary reality. The reason it doesn't work is partly because the right people aren't in office to implement it, and partly because when the right people are in office they don't have enough time in office to implement it fully.

Get someone with the right intentions in office (a progressive), and give them enough time (at least two terms), with a congress that supports their agenda, and you'll see incrementalism work as it's intended.

Or you can complain that you can't have everything you want immediately, and attack anyone who doesn't give you everything you want right now, and when they never get into office for long enough with enough congressional support because nobody can pass your purity test, you'll have plenty to complain about when literally nothing good gets done because you categorically rejected the idea of incrementalism.
