For Marx, economic equality would not simply consist of what we have in a capitalist system which is (ideally) the equality of economic opportunity. Instead, there would be equality of economic results. This would not mean that every person would have the exact same amount of every sort of good. Instead, it would mean that everyone would have what they needed. If different people had different needs, they would get different things. But the point would be that they would all have everything they need. This can be captured in the famous line in which Marx says that an ideal economy would work according to the slogan "from each according to his ability, to each according to his need."
