What Is the Rate of Exploitation?

In the macdonald's example i gave earlier, they work four hours to earn enough to cover the cost of living and all that. Then the next four hours is surplus labor time. That is the exploited amount that goes to the capitalist. This signals a rate of exploitation of a hundred %. The capitalists will say, i can just pay the worker forty dollars for eight hours of work,. So in four hours of labor time, they aren't actually earning or making back what they need to survive. They are only making it back after eight hours. But they are making the capitalist so much more that they are able. And this puts us here into chapter ten, the working day.
