““What if economic security and guilt-free sexual friendships were easily available to almost all men and women, as they are in many of the societies we’ve discussed, as well as among our closest primate cousins? What if no woman had to worry that a ruptured relationship would leave her and her children destitute and vulnerable? What if average guys knew they’d never have to worry about finding someone to love? What if we didn’t all grow up hearing that true love is obsessive and possessive? What if, like the Mosuo, we revered the dignity and autonomy of those we loved? What if, in other words, sex, love, and economic security were as available to us as they were to our ancestors? If fear is removed from jealousy, what’s left?””
