I agree with this. Ideally we'd try to find a system resistant to this kind of corruption longterm, but from what I've seen, if you have a system that resists corruption, once that corruption inevitably sets in (and it always will), that corruption will have commandeered the means intended to prevent it from taking root, thus entrenching it far deeper than it would be otherwise. A system that takes a decade to corrupt might only take a single election to fix, whereas a system that takes a century to corrupt will be almost impossible to fix, and then you're just stuck waiting for its inevitable collapse centuries later.

I don't think there's an actual solution to this problem, aside from Jefferson's "tree of liberty" quote, and even that isn't a particularly viable long term solution.
