This is the purpose of federalism—to manage governance by and for smaller, like-minded groups of people. However, people seem to have a hard time staying out of each other’s business. Furthermore, it’s hard to justify a hands-off approach when a state or lower level of government is using 55% majority to oppress the other 45% (see the American South). And maybe most importantly, it’s always in the interest of national leaders to increase their power, so we tend to see a steady creep of stronger national governments at the expense of states or smaller units.

I suspect there are ways to counteract these forces but we’ve yet to trial most of them. Ideally you want your basic level of government to be as small and like-minded as possible. But I think to avoid tyranny of the majority, you need to let people opt out. Most people don’t seem to be too aware of these issues in the constant struggle for ultimate power but I think it would solve a lot of our issues if we just let more people live how they want to live.

So I agree that smaller democracies work better, but I hope you’re not saying the solution for larger democracies is to make them not democracies. The solution to me is clearly that we need to make them smaller again.
