except cavemen enjoyed 100% of the fruits of their labor. a caveman who produced 5 animal hides had 5 animal hides to himself to do with as he saw fit. an animal you killed was yours, a fruit you picked was yours. in modern times you work more hours and your labor is able to produce exponentially more value than just a single animal hide due to our sophisticated labor-saving technologies. however, the wage you receive in return is a minuscule fraction of what you produce.
