There have been tons of protests recent years. I think in the near future there will be one so large that America will come to a halt and either the government will act and fighting will start, or something will be done to address the protesters grievances.
The protests will be one or more about wages, health care, taxes, government priorities when it comes to funding and what taxes are spent on, housing costs, food costs, goods costs, corruption within the government, college costs. Most likely a combo of all.
Every day people have less and less to lose.
