The way things are owned affects how the rewards of work are shared out. Different systems of ownership lead to different ways of dividing up the things people make. In a market economy, the money made from work can be split up in three main ways: treating the things used to make stuff as things to sell, as things that make money, or as money itself. No matter how it's split, who owns the things used to make stuff is what decides how the money is shared out, not how much work went into making it. But even though how much work goes into making something doesn't decide how the money is shared out, it still has a connection to who gets what.
