I don't think Musk strived to become rich, his ambitions made him so.

Seven Social Sins is a list that Gandhi published in his weekly newspaper Young India on October 22, 1925. Later he gave this same list to his grandson, Arun Gandhi, written on a piece of paper on their final day together shortly before his assassination. The Seven Sins are:

Wealth without work.
Pleasure without conscience.
Knowledge without character.
Commerce without morality.
Science without humanity.
Religion without sacrifice.
Politics without principle.
