It's not actually the instability as such (I think), but the scale of the power and decision-making. The US in particular has centralized a ton of power and decision-making in Washington, where the original vision (at least among the early Federalists) would be that the federal government would remain weak and the power would be largely left in the hands of the states. If government were better-federated, to push the power and decision-making to smaller and smaller units, then citizen buy-in would be a lot easier because the answer would always be "get involved in your local legislature", not "cast your vote into an ocean of millions of votes and hope for the best". Americans sometimes look at Iceland as an example of Scandinavian Utopia, but I think the single best thing Iceland has done that's the cause to a lot of the effects has been to stay small. It's easy to know someone in government personally even if you're an outsider. Sure, there's still corruption and centralization of power and wealth, but the scale is so much smaller that it's a lot easier to just kind of shrug it off than when the fate of the world's data is at stake.
