Respectfully, the person paying you is your customer by definition. That's sort of my point: the people paying teachers do not want to buy teaching because they don't actually care about the next generation. At best they want babysitting. The same people DEMAND ez credit and cheap plastic shit in Walmart. So they pay the bankers who are key to producing those things handsomely.
The person paying is the customer. The person receiving the service is a "cost centre" in basically all underpaid, "socially useful" roles.
