This is the argument which took Obamacare from being a big bold progressive transformation to the American medical system and made it worthless; the same framework that led Obama to make only incremental reforms when Americans were demanding sweeping changes: this argument of incrementalism is why fascism got a toehold in the US, and the insistence on the idealogically of incrementalism on the part of alleged allies is why fascism has taken over almost entirely.

The politics of half a loaf is why the American system is falling apart. It's not a way forwards.
