Marxism and Exploitation

Exploitation when it occurs, usually it's a positive sum game and that's why workers voluntarily accept to being exploited. It's better to be exploited under capitalism than not be exploited at all, not being employed at all. You do a great job describing and summarizing dozens and dozens of studies and what they say on balance. So maybe we don't have to hit all of them but one of the things you take on is exploitation. How does capitalism fare with regard to exploitation? Good topic for you to take on coming from a Marxist perspective.
