Not yet sure if I'm supporting Sanders, but I wish he made a better argument that these policies are better for us all. A healthy population benefits us all. An educated population benefits us all. There is a direct correlation between low education, low income earners and crime. And if those 1%ers, instead of increasing the prices of goods to make up for an increase to taxes, gave workers a livable wage, we would see a decrease in societal ills. Less crime, less dependency on the state, etc. But that would hurt their and their stakeholder's bottom line so....
I don't know if this sort of class warfare will resonate with moderates, who are pretty much all-in when it comes to capitalist systems.
