It's not all about the odds. Sure at an aggregate level it might make sense. But instead of looking at it as mere % expected return, look at it as a tiered return. Above 200K I'd need 1M+ a year to improve my life. Above that, I'd need 10M+ a year. Above that 50M, then 500M and then 4B a year etc.

The quality of life improvement varies in the income bracket. Not every % increase is equal for individual humans.
