Georgia is an interesting outlier here: they introduced the HOPE scholarship in the 1990s to allow any in-state (already lived there for at least a year) student free tuition at a state school as long as they maintained a 3.0 GPA, all funded by the state lottery.

And you have some pretty good schools to choose from here: University of Georgia, Georgia Tech, and Georgia State (which has improved a lot in the past 10 years).

There are plenty of fair criticisms that can be leveled against the HOPE scholarship, but it seemed clear to me that it would reduce brain drain in the state, simply because students could get a high quality education at almost no cost. But these data show that the drain ratio increased from 1990 to 2010.

So this is a situation where students aren't paying for their education, are going to school in the state where they likely grew up, and then are still leaving.
