I work in a factory where it’s about 50/50. Most of my black friends here have a wife and a girlfriend or two. It’s just a common thing with them. Most of my white friends don’t. There are some huge social issues I have with mixed marriage. With that being said, I point out just as many flaws with white trash too when talking with my kids.
I just simply tell my kids that whatever decision you make will determine what kind of life you have, easy/good or hard. Talk about these things early and often, and they’ll start watching how “others” live.
