So the ultimate question is: how do we make sales executives look like a threat to profit margins?

The only way I can think of is to make profits above a certain level unprofitable by taxing them at a high rate with ratcheting without bracketing (i.e. any amount up to $X billion taxed at 10%, but anything greater than $X + $0.01 will be taxed at 60% for the entire amount, resulting in a tax graph that is discontinuous for profit vs. tax). Profits can be tinkered with, so perhaps do that with revenue instead. Then, for companies of a certain size will have no need for sales executives, and will be punished by Wall Street for exceeding optimal sales targets.

This will make whole internet fragmented, why serve customers beyond revenue target, so best products will be available only to most profitable customers.

One could say the car industry is also "fragmented": but we have up-market OEMs and Toyota/Honda.

Isn’t this already the common theme in capitalism?
