Hollywood can never represent anything realistically. The most recent trend of progressive theater that cannot get the story straight is the concept of interracial relationships in America. In this realm, Hispanics become a separate race to boost numbers since white-Hispanic pairings make up 43% of all interracial marriages. These marriages happen at low rates, but the dynamics of each type of pairing vary wildly. Divorce risks jump significantly for most pairings (especially for anyone marrying a white woman). There is one large exception. The pairing with the lowest divorce rate is the white male-black female pairing. It's shockingly out of step with all others. The next closest rate of divorce is white male-Asian female, which is a touch higher than the white-white baseline (hmm, white guys marrying out don't seem to be the problem). Anyone ever say why? Number of college degrees for the wives is brought up but nothing about what really makes things click because writers would have to bring up modern day unmentionables. Looking at the pool of men, the pool of women, who initiates divorce and the sexual marketplace, the lower divorce rate makes more sense.
Let's use OKCupid for some help. OKCupid's data seems to point to white guys being picked for exclusivity even more by Hispanic and Asian women than with white women. White guys also make pretty good money. They also seem to have fewer kids out of wedlock. If you're looking for husband material, white guys seem to be a good catch. Marriage itself has also become a middle class and upper class thing (thanks progs), so the type of white guy making the decision to marry is most likely earning some dough and looking to raise a family because what idiot is locking into one woman forever if he doesn't want kids. Let's use OKCupid's data again (it's a great OKCupid post) or Kanazawa's study for black women. Just relaying study results. As far as the sexual marketplace goes, not all that high of value. As far as making money or wealth, not all that high either. As far as getting married, not all that many black women getting married either.
How do people meet their spouses? School, work, social circle or activities with their social circle. On the socioeconomic scale, we're probably talking about a setting with a higher percentage of whites than blacks (even Obama's campaign events). To borrow from the other explanation, possibly a higher household income and educational attainment levels. Oddly enough, the percentage of BF-WM couples where both have colleges degrees has dropped since 1980, yet the divorce rate remains well below the white-white average. In the unmentionables realm, you've got one member of a group that has pretty high value as a whole pairing with another member from a group with lower value. In a world of declining commitment, a man marrying is putting up stakes and locking one woman down. These white guys are selected at high rates by all groups of women and are committing to a woman from a group that has been assigned a lower value in the mating marketplace.
Think about what you see with these pairings. He might be a SWPL, he might be an Ed Hardy t-shirt guy, but she is going to be thin and attractive. Isn't that all modern white men really want? That must eliminate some divorces from the frivolous and superficial crowd, but women initiate 2/3 of all divorces. He's happy with her physically, and ahem, what's the trade up for the lady if she leaves? If she divorces, what is her lifeboat or escape plan? Isn't one of the thoughts behind the lower divorce rate for older brides the idea that she is older and has fewer options when she gets the seven year itch? Who is she going to find 7-10 years after exhaling at the altar? A woman who has made such a lifetime commitment selection, breaking away from a group that demands such conformity as modern America's African-American community, might be attuned to what her options are. Google good brotha shortage. Suddenly that lower divorce rate makes more sense doesn't it?
Hollywood, America's cultural brainwashing machine, might be catching on. Hollywood still has not recognized that 21% of America is Hispanic and Asian, and they commonly show interracial relationships that are black males and white females. That pairing is always happily married with both spouses having good jobs and healthy BMIs. The most common interracial marriage pairing in America is white male-Asian female, but Hollywood has shown this when? Hmmm, there was one over fifteen years ago on "The Single Guy". Grey's Anatomy had a temporary fling, right? I never see them on commercials, even for high end products which couples who met at Cornell's engineering school would definitely buy. Blacks are still the go-to minority Hollywood uses with regularity. Casting directors might be seeing couples at Whole Foods like I have. Recently Hollywood has cast black actresses with white boyfriends or husbands. Kerry Washington, Zoe Saldana, Sanaa Lathan and Halle Berry have been paired with white paramours. The tell that Hollywood might recognize the reality of the white male-black female pairing: the white male-black female pairing is a stable relationship not present just for comic relief.
