Yes, just as with my example with the middle class families, their social circles are so close that they intertwine.I'm not disagreeing with you, but something I have noticed is... and this may be what ssj4sadie is trying to point out.... I have seen plenty of black families in trailer parks, with pickup truck and lovin' some Skynyrd; and I have seen plenty of white families living in poor inner city neighborhoods that turn up with fetty wap.
