You can try to put the blame on the grunts, like trying to focus on the engineers in the VW Dieselgate, etc, but that is very weak leverage. You have to intervene at the root cause of the incentive. But of course the higher you go, the more there is a blur between legislators and business owners and they won't be harsh to themselves.

So morals are good at a certain pay level?

Thank god I am just a minion who now can go home worry free. Yay!
