First, the US is a WAAY to large country for any kind of revolution, and certainly the people are still expecting help and some need the support of the goverment to live, so you just cant.
A revolution would tear the country apart into independent states or even less.
Also you are in a point that the goverment has a HUGE, HUGE, military machine, that can crush anything and will not hesitate to slaughter its own citizens.
Most people dont want anything to change
See the movie ''Network'' and your mind will be blown, explains it all

As said, i dont see any other solution but plot with a group of military dissidents or military officers who are not happy and want change, you can plot a coup from there.
Assassinations, always, best option, assassination of military elites, bankers, dont forget, federal reserve staff and other elite of the elite, dont think you should botter with politicians, they are not the authority there
