How many people could we educate this way, for the price of having one study at USA.
Many, but that assumes that the actual quality of the education matters (the most), and not something else, like the opportunity to meet other people who will make up the elite class in the future.
It would even make sense for US citizens to study abroad for economical reasons, if they can’t get admitted to an elite US school, but how many future political leaders aren’t elite school graduates?
Imagine a 3rd world country, where if the person graduates their best university, most people with real influence won’t even be aware of its existence, or of the existence of the city where it’s located. How much can that person do? How much more could they do with better networking opportunities?
