It's just harder to get the average joe charged up to fight a battle with anything meaningful on the line. Americans are used to living relatively cushy lives where they don't sacrifice their QOL to make the lives of their countrymen better. The closest thing to that are people in the military, and it's probably been a while since the US military is improving QOL, on average.

People will continue to be complacent on multiple fronts until it absolutely comes to a violent boil. I don't really see half measures or peaceful protests changing anything. And maybe I'm pessimistic, but I think the upcoming elections will either not change enough or be strongly manipulated to maintain the status quo.
