Marriage works, at least on a billboard

“Married people earn more money,” said the ad I saw on the way to the post office here in Baltimore yesterday afternoon. I was intrigued. I could always use more money, and perhaps Marriage Works USA was offering to help. Did they introduce young singles? Ship in girls from Eastern Europe? I had to know more. Actually, I didn’t. Turns out it’s a Web site put together by Campaign For Our Children that yammers on about how awesome marriage is without offering much specific advice.
