Your mother may love you, your friends adore you, and your enemies lie prostrate in awe — but you aren’t worth ten cents on the market for being “you”; your value there depends almost entirely on your productivity. If you cannot contribute to a productive process, you are worthless . . . and it is unfair for you to demand of anyone anything more than what they may willingly pay you. It is especially unfair to demand support from those who have developed skills valuable to others while you have not.
Marginal utility: what is yours?
