A new television program will soon be showing an apparently happy polygamous family. If, one might ask, if gay marriages are OK why not marriages with multiple partners? A very thoughtful article on the why nots starting with all the men who won’t get wives.
In summary:
“The problem in China and India is sex-selective abortion (and sometimes infanticide), not polygamy; where the marriage market is concerned, however, the two are functional equivalents. In their book, Hudson and den Boer note that “bare branches are more likely than other males to turn to vice and violence.” To get ahead, they “may turn to appropriation of resources, using force if necessary.” Such men are ripe for recruitment by gangs, and in groups they “exhibit even more exaggerated risky and violent behavior.” The result is “a significant increase in societal, and possibly intersocietal, violence.”
Crime rates, according to the authors, tend to be higher in polygynous societies. Worse, “high-sex-ratio societies are governable only by authoritarian regimes capable of suppressing violence at home and exporting it abroad through colonization or war.” In medieval Portugal, “the regime would send bare branches on foreign adventures of conquest and colonization.” (An equivalent today may be jihad.) In 19th-century China, where as many as 25 percent of men were unable to marry, “these young men became natural recruits for bandit gangs and local militia,” which nearly toppled the government. In what is now Taiwan, unattached males fomented regular revolts and became “entrepreneurs of violence.”
This sounds a lot like what’s happening in much of sub-saharan Africa today.
