People never leaving small towns

Creeps me out. 
Now I'm not saying that small town living isn't awesome, I just truly believe you cannot be a fully functioning member of society if you never left that small town ever. 
I believe these kids need to graduate HS and move off somewhere to do something different for a minute. If they decide to move back, GREAT. If not, GREAT. But small town mentality is what is killing this world right now.
