It used to be that high school grads would leave their hometowns to experience life in college — then return home once they got their sheepskins.

Others would spend a year or two in New York or Chicago and, after getting the big city out of their systems, return to a city like Erie when they are ready to settle down and have families.

Of course, we all know that isn’t happening as often in Erie as it used to be.

This entire site was built on Erie’s so-called “brain drain” — and this diaspora of Erie people to other cities is what has helped sustain GlobalErie into its second year.

Now, we find that there is a potentially unexpected echo drain.

Author and scholar Richard Florida of The Rise of the Creative Class fame predicts that, increasingly, boomer parents will be moving to other cities to live closer to their grown children.

If that happens, not only will we be seeing our young talent leave. We’ll see their well-heeled parents picking up stakes and leaving.

Based on my own experience, Florida’s prediction doesn’t seem that far off. My only sibling lives only about 30 minutes from me and my parents are seriously considering leaving Rochester, N.Y., after they retire to move closer to their children and grandchildren. And the New York Times writes of the growth in the number of parents following their children to college.

If others are considering similar moves, Erie could be facing a wave of monied retirees moving out of town.

Does this possibility worry you? Is it an unreasonable prediction? I’d love to hear what you think.
