Socialism works. But not many people know exactly what it is. They just listen to their parents who grew up during the "socialism is an evil Russian plot" era. Taxes, for example, is a socialist idea when implemented correctly.
Everyone contributes, and everyone benefits. Health care, child care, elderly care, income equality, economic safeguards and stability, work place negotiating, etc.
I agree that Socialism can work. Like everything else, it is almost never all one way or the other way. It seems to pivot on the will of the people to make it work.
