I equate Bernie Sanders w [the] Donald Trump [movement]. Both are cries for help in a rotting political system of perpetual self service rather than a political system in service of the people/greater good.
Until someone/something changes that trajectory we will see a slow but steady drumbeat for revolution from both sides.
IMO, this is an extremely dangerous time for America in which we can stumble into a major war, distracting us from what is happening at home. Besides the obvious, a question is whether that would unify us as WWII did or divide us as the Vietnam conflict did, furthering the current climate.
Put it another way: The MLK movement of non violence didn't quite fit the American ethos so along came Malcolm X and The Black Panthers. That really got the conversation going. Do you see some similarities in the ebb & flow of our current politics?
