Fundamentally if your needs are met ie you have food on the table and your kids can go to a decent school then what more can you want? It seems socialists have more of a disdain for the rich than their sympathy with the worker. The idea of capitalism is to provide the ability for social mobility by either 1 increasing your labour value through education/hardwork and 2 investing and acquiring some means of production to be in business yourself. Equality of opportunity not outcome is what I want.You consider exploitation to be efficient?
