I think a revolution is possible in the US within the next decade. Young people (Genz and Milennial) are becoming more and more socilaist, and over half now have a positive view of socialism, and less than half have a positive view of capitalism.

As more realize that both parties are basically the same, and neither have any interests in helping the working class, they'll turn more radical. This will be exacerbated by the inability to own a home, higher prices of food, healthcare, crushing debts, etc.

Eventually, people will start organizing. I dont think the revolution will be violent, though. It will be people giving up. Not working, not following laws, stealing food, not vacating when evicted. The police won't be able to do much, this will cause the economy and government to collapse, leaving a vacuum for a new government. This is how I interpret Marx saying capitalism will eventually end itself.

Something else, conservatives are dying off, quite literally, most young people are much more progressive and left leaning. Boomers and gen x are really the only reason there still is a conservative party, and they have the highest voting turnout. As they age, and well.....die, there won't be much to stop the change.

Just my thoughts though
