Sure. College, which ends. After that, returning to your hometown is only possible if you're privileged enough to be born somewhere with a decent local economy, and even then, chances are you'll be moving from family-oriented suburbs to an "up-and-coming" urban neighborhood with other young adults... same set of issues. Or you got priced out of the Bay Area, or your hometown's economy finally shrank to below the level where it can sustain you, etc.
