So if the apples are in a 3.5m high tree and you're 2m tall and I'm 1.5m tall, it's fair if we both get 1m ladders?
Yes? Maybe the 1.5 m tall guy should find another line of work where he has a natural advantage that could be turned into profit. People are not the same. The market is the best way to allocate resources fairly to people of different ability
why isnt it fair?
Someone taller has a better chance at becoming a pro basketball player. Shorter people are not given more leeway. But both tall and short people have the chance to try out (at least on paper).
