That's not a fair statement.

Every institution (let's say - my household) sweeps problems under the rug. It's the euphemism for problems that aren't worth dealing with.

Institutions (in the form discussed) are either reinvented from the inside out and thus are and remain institutions, or are "toppled" in which case they are not "institutions" but "failures".

Think of how the Tea Party and the Libertarian movements or affected Republican politics in years past, or how completely alien the party is compared to a decade ago. The institution of the "Republican party" persists, even though it's nothing like its former self.

Same name, same "it's all fine just keep trusting us" but meanwhile quietly burned to the ground from the inside out.

The backdrop is that centrism is failing everywhere. Macron's France is a great example but you can see it in Starmer's Britain. It might be sensible policy but it doesn't satisfy anyone emotionally whereas Trumpism does. Of course "satisfied emotionally" can leave you with one hell of a hangover the next day.
