I'm probably projecting the idea I have of myself here but if someone says

> every exchange is about what's best for humanity and the public in general

it means that they are the kind of individual who deeply care for things to work, relationships to be good and fruitful and thus if they made someone pay for something, they think they must listen to them and comply their requests, because well, they are a paying customer and the customer is always right, they gave me their money etc etc
