This trait is also very prominent in inhabitants of the west coast, particularly California.
It's just disgusting all the way around.
None of us native Californians write off the rest of the country as “fly-over” country. Why would we? We’re in the same boat as you. New Yorkers have been looking down their Charlie Rose half-glasses and sniffing at our backwardness since the first Rose Parade.
The “Californians” you’re thinking of are transplants who migrated here to work in the entertainment industry. Also carpetbagging politicians like Nancy Pelosi and Barbara Boxer. The people who decide what you’re going to watch on TV and at the movies and who pass legislation that’s ruining the whole country might own fat houses here... but they’re not Californians.
By the way, I’ve been to Tupelo. What a lovely town! I’d love to live somewhere like that... but I work in the entertainment industry, so here I stay.
