At least for children who grow up with married parents, there's still quite a bit of income mobility. Such children born into the bottom quintile of income, are pretty likely to end up in any quintile. The probability of ending up in each quintile from bottom to top, is 17%, 23%, 20%, 20%, 19%. Seems pretty fair to me; totally fair would be 20% chance of each. It's a little skewed for people born into the top quintile, but not so much: 10%, 13%, 21%, 27%, 30%.
