Income brackets are not as sticky as you might think[1]. If you are in the second or third quintile, you are more likely to move income quintiles than stay where you are over ten years.

If you are in the bottom quintile, you only have a 64% chance of staying there. That's not incredible, but it does make you question the "inescapable poverty" narrative when a full 1/3 of impoverished people escape it every decade.

Across every income quintile, you are more likely to die richer than your father[2].
