No, I agree that I'm progressive in some ways. I agree also that politicians have found loopholes by building up the executive branch (as in the signing of executive orders), bypassing the dysfunctional Congress too.
But it's a strawman to say the progressive thinks that what's new is automatically what's good. That's nowhere near the logic. Indeed, I've critiqued much of modernity, such as capitalism and democracy, as well as scientific objectivity, so I don't automatically accept revolutions just because they're recent. We need to weigh revolutions against the thrust of history, keeping the big picture in mind just to check whether the revolutions are as transformative as they might seem.
But your last point seems consistent with what I'm saying. Why not restructure the Constitution to address the new temptations of plutocracy? It's a pipe dream, of course, and anyway, I'm saying the people should change their society by going around politics, just as the wealthy elites do.
