History shows revolution almost always ends in civil war and destroyed infrastructure. You can't just create a power vacuum with nothing to fill it.
Even if you do manage revolution on a unified front, it always seems to splinter within a generation unless something radically new from some outside source forces you to alter or die.
The best revolutions start with an abdication and reform, reform, reform.
The only way i see that happeniing in the US is if everyone started voting third party and stopped being a two party system. That would create some competiton among the ruling elite.
