You need jobs to have public services, public infrastructure, and both essential and nonessential goods. The overexploitation of workers and the lack of democratic ownership of the workers in businesses is the problem. Profit can still be made and go towards wages and back into the business, even better when subsidies and workers protection/rights are guaranteed federally. We can't have a functioning society without jobs
Public refers to government, yes. The difference is a socialist mode of production where the workers own, in a democratic organization, all the decisions of the business. In this kind of organization the workers decided democratically what they are paid, what trajectory the business has, and everything else. The goal is not one of maximizing profit year over year as in the capitalist mode of production. That's why I differentiated exploitation and over-expoitation. I'm using the marxian definition of exploitation. Here, Richard Wolff has a comprehensive explanation of the different modes of production and how that impacts the workers.
If you have no interest in understanding the difference between the socialist and capitalist Mode of Production; even after listening to the detailed and easy to understand explanation by economist Richard Wolff, I don't have an interest in this conversation
