I would not consider the American Revolution a reset, it was a complete change, the English monarchy/oligarchy no longer had control over the people of the USA.

A government structure/system is never static, there will always be changes (some minor some drastic) the question is are the people in charge creating system changes that benefit the majority of the population that live under that system or are they benefiting the minority wealthy who live under that system.

When the system changes that are made by the people in charge (this can take years, decades), keep making life more and more difficult for the majority, a breaking point is eventually reached, the people at the bottom want change and they want it now. They no longer want to enact change with peaceful reform and they choose violence and rioting.

Unfortunately the wealth inequality in the USA is the highest it has ever been (not only USA this is a global problem). This violence and rioting in my opinion will continue to escalate unless drastic changes are made to improve the lives of the majority of the population...
