Is it worse for a person of European DNA to mix with DNA of non-Europeans, or is it more a plus for non-Europeans to mix DNA with Europeans?

Following the interaction of this question, I got to thinking about my experiences in the past and wondered if others had experienced similar, or if it happened in other areas? When I was a kid, it was seen as a plus to be mixed with white; lighter skin, ”good hair”, etc. the teachers and merchants seem to treat you better and the cops did not jack you up as much. On the flip side, if you were white, and mixed with non-white blood it was seen as a step down; the non-white blood seem to hurt them worse than it helped non-white to mix into it. If you could not mix with white, Hispanic was the next best choice, still had nice bronze skin tone, ”good hair”, and features, etc. Asian and Black was so rare you could get hit with a meteor before you seen that union. In another word, an affluent white person would still be better off mating with a white person seen as ”poor white trash” than with Black or Hispanic (OK, Hispanic did not hurt as much), but Asian seemed to be OK, unless it was the really older people who still were seething over WWII. How was race perceived, handled, or seen where you grew up, and what era was it (decade wise)?
