I don’t think the American governments biggest problem is it’s scope and power: I think it’s biggest problem is inefficiency due to corruption (regulatory capture, etc). It seems to me that the biggest obstacle to fixing this is that many Americans see this as an inevitable character of government rather than something specific to their system, and thus spend their time trying to reduce government (ironically making it even less effective by hobbling it with silly restrictions) rather than fixing it into a well functioning system.

The two are interrelated — regulatory capture doesn’t make sense if there’s no power to capture. So one must first grow the size and power of government through other means, then capture/influence that power. This cycle has been going on for a long time.

One of the amendments is supposed to shield you from tyranny. But, going down a less risky path, I'd vote (no pun) for migration. My parents migrated away from a country that trades in humans to this day, in full view of the gov, and i can't be thankful enough.
