Well, that's the system that was set up over 200 years ago, and I'm pretty sure there have always been unhappy people.
When the system doesn't work there is one solution only - civil war and changing it - so the question is do you think that would make everything better? Do you have a better system in mind? I mean the one that works better when the guys you don't like are in charge, because unless you're the dictator there will always be times when you don't like the person in charge.

The real issue is that revolutions and tearing down is relatively easy compared to building something better afterwards.

I'm not sure about the issue you're referring but my thinking is that when you set up extrajudiciary process out of expediency or whatever it cuts both ways - the executive gets full control of what happens without interference from the judiciary.
