I remember in econ101 the professor showed the supply demand curve graph and explained consumer surplus and how it was inefficient because there were consumers willing to pay more but the supplier had to set a single, optimal price. The professor went on for a few minutes on how dynamic pricing per consumer would maybe be possible one day to realize this and how much more money would make. But he said ultimately it wasn’t fair and he was glad it was “impossible.”
