That is not correct. A person who flips burgers and a person who is going to school to learn a trade are both using an equal amount of time. The latter however expended more effort to obtain a skill set and effort and labor are equivalent. A 40 year old who works 12 hour shifts to make ends meet can use more time than an individual who expended effort to train a skill to proficiency and enter a labor market. Additionally, we can have 2 individuals who both spent time training a skill set. One can end up more proficient than the other despite time or effort spent as despite the old adage not everyone is created equal. Some are prodigiously gifted. One person may struggle through his tutelage while the other breezes through. In the end they both put in the same time, 4yrs, do they get paid the same because they put in the same time? On the contrary, I went to school with several people that made it through the program for CS and got the paper, but are working in hospitality, warehouses, or sheet metal. They put in equal time do they all get paid equally?
