Not really. The point of a government is to be the big intimidating force that keeps would-be exploitative forces in check, but it's now owned and run by those very people. The second amendment was made for this exact scenario, because when the big brother protecting you from bullies becomes a bully, the only one left to put up a fight is you.

I have bad news: real way is to stop producing humans like what we have now in the upper class. Unless this is done, best we can get is a periodic cleansing, until next time of "well, things went to shit again"
