> A rich college graduate has almost 2x the chance of remaining rich as a poor graduate has of getting rich. This is all super fuzzy and almost impossible to interpret. It sounds to me like people are becoming rich at some rate, and staying rich at a higher rate. Seems like it would lead to everyone being rich, in the end (though these are quintile numbers, so it's a relative ranking, so I assume some other outcomes are available that make things balance).
