Capitalism-at least as Sanders & Co. understand it-is not fulfilling. It doesn't provide a sense of meaning and solidarity. It rewards-in their minds-the few and punishes the many. There must be a better, more humane way, in which we're all in it together and sacrifice is shared. The word "social” comes from the Latin socii, meaning allies. People want to feel that they are allied with one another, fighting toward a common goal together for the good of the tribe, marching to the same drumbeats. This is innate in us. Our tribal brains crave social solidarity every bit as much as our palates crave foods that are sweet, fatty, or salty. We can train ourselves to resist the cravings or channel them toward productive ends. But very few of us can eliminate the craving itself.
