> I'm not sure I follow. So, thinking out loud... a billion dollars at $10 a ride, so lots of transactions, lots of customers. Theory says a transaction will only happen if both sides feel they will profit, so lots of people must have benefited, right? But no, because you were talking about the total benefit, not total number of people who benefit. Trivially, if the customers got a ride plus a share of a billion dollars, they'd be better off than if they just got the ride. More benefit would be delivered to customers if Uber had zero revenue, so using a massive revenue figure as a measure of value delivered to customers is meaningless. But, the guy might still be on to something, since Uber benefiting lots of people only a little may still be more total benefit than some free software that hardly anyone uses, he just needs to back that idea up with something more substantial.
