“In strict Muslim countries such as Afghanistan, many young men have little hope of ever finding a partner. Typically in such nations, there are at least 3 percent more males than females, partly because females don’t receive the same medical care as males. Also, polygamy means that the wealthiest men take two or three wives, leaving even fewer women available for the poor. The inability of a young man to settle down in a family may increase the likelihood of his drifting toward violence.”
