“Money doesn’t buy happiness” actualy just statistical error. Average person is happy with money. Unhappiness Musk, who has 900 billion dollars and is incredibly pathetic and unhappy, is an outlier adn should not have been counted.
Especially because there are other factors that play into happiness like a stable love life, no criminal activity hanging over your head, and being attractive- all things Elon doesn’t have going for him right now.
