A great many people conclude that something can't be evil if they are profiting from it - Charlie Munger

A great business at a fair price is superior to a fair business at a great price.

And the models have to come from multiple disciplines — because all the wisdom of the world is not to be found in one little academic department. That’s why poetry professors, by and large, are so unwise in a worldly sense. They don’t have enough models in their heads. So you’ve got to have models across a fair array of disciplines.

It is not always recognized that to unction best, morality should sometimes appear unfair, like most worldly outcomes. The craving for perfect fairness causes a lot of terrible problems in system function. Some systems should be made deliberately unfair to individuals because they'll be fairer on on average for all of us. Thus, there can be virtue in apparent non-fairness.
