Most social revolutions only occurred because the people in charge were incompetent and almost completely clueless. As long as the regime can co-opt (or otherwise remove) the potential leaders of this revolution and commit to some modest reforms it can survive almost indefinitely (without external interference, e.g. climate change, plague or war) at least this seems to have almost always been the case historically.

The USA has gone through periods of high inequality before without relying on revolutions to solve the problem. Higher taxes on income and wealth, more support programs for the poor, etc… our political system is robust enough that we can solve our problems without shooting each other (I hope).

Half of the country thinks that doing those things will literally destroy the country. The other half is willing to compromise with the first half. The same folks who preach no compromise, and tend to own more than one gun apiece.

Not holding my breath here.
