I think you get less exposure to the rich vs. poor thing when you live in a suburban community. You're more likely to be around people whose household incomes are similar.

I grew up in a very small town where the incomes spanned the spectrum... in a tiny geographical area. My best friend's family's backyard abutted ours. Her house had 5 bathrooms, a butler, gardeners and a guest house, while the house I lived in could have fit in her living room. Her family had loads of money and my family didn't have much... but we had enough to get by. My dad used to refer to our house as the "caretaker's cottage." LOL.

My high school had kids whose parents were millionaires and kids who lived in shacks.
