Unfortunately, the decreasing mobility in US is partially responsible for the growing parochialism of vast swathes of America. And i don't automatically mean - Midwest, if you were born in LA or NYC and never left, at least for couple years, your mind is as fucked... just in a different way. And it's totally kosher to come back, but only AFTER experiencing the cultural "otherness" of a new, distant location.
“In his book Innocents Abroad, Mark Twain stated: 'Travel is fatal to prejudice, bigotry, and narrow-mindedness, and many of our people need it sorely on these accounts. Broad, wholesome, charitable views of men and things cannot be acquired by vegetating in one little corner of the earth all one's lifetime.'”
