The total lack of any sympathy for the difficulties of the very wealthy often reveals an underlying belief that all *your* difficulties in life are a result of simply not having enough money.
Imagine you gain billions of dollars. Fast forward a year or two - what are your biggest difficulties? Are you any happier? Do you still experience anxiety? All your problems now are definitely rooted in you, not your want for material things.
I think many intrinsic worries would grow with the scale. Fear of loss is the same but larger because there is more to be lost. FOMO is larger because everything is massive opportunity cost. Selfish leechy friends are more abundant and harder to root out
Is it possible that an unhealthy obsession with wealth was causing the stress? I have a friend whose F-Advisor told him that if he never made another dollar and made no spending adjustments, he'd run out of money at 87 years old. And my friend freaked. He's 49 and still working.
