All revolutions have unexpected consequences.
And the 'free love' sexual revolution that began in the 1960's is no exception. Yes, there are the obvious consequences: STI's, children born out of wedlock, a 'pornified culture' and so on. But there are also the unexpected - and surprising - consequences.
As it turns out, these unexpected consequences hurt women in particular. And economics - of all things! - shines the light on one such consequence: From a Christian worldview perspective, taking sex outside of marriage will always have negative consequences. After all, sex and marriage were designed by God, for our good. And using such a gift against the Maker's instructions will always have awful consequences.
Welcome to the revolution.
