In the South, its (depending on where) Black folks, in Texas, New Mexico and Oklahoma, its Hispanic.
The fact that I see mexican/hispanic restaurants and groceries, in rural america (even in the south) tells me the world is changing.
Imo there should be a cultural exchange program where you students in cities and send them to rural schools for a semester and vice versa via exchanges. It's important to the American experience to be able to understand both worlds if we are going to continue to coexist in a union.
I've long believed in some form of mandatory national service, just to encourage this - it would also decrease the risk for military adventurism if the military was a broader cross-section of society.
So if rural America is gradually becoming that way, and thereby the rest of the world following suit, I guess the reason to travel would be to experience different cultures before they effectively come to us all (or disappear all together in some cases). But that's really more curiosity than anything else, like visiting a traveling museum exhibit that has a limited run.
However, I must admit I may be wrong in my interpretation of this, and now I want to ask my dad again next time I see him.
It is a great idea, nevertheless.
