The media is smitten with news about the royal engagement between Britain's Prince Harry and American movie star Meghan Markle. The two announced they'll marry in the spring. But marriage isn't just good for movie stars and royal families. It's good for the overall health and economic well-being of men and women. A report by the American Enterprise Institute and the Institute for Family Studies found that young men raised by married parents earn an average of $6,500 more than boys growing up in single parent homes. And married men between the age of 28-30 make about $16,000 more on average than their single counterparts. There's a lot of talk about income inequality these days, but the biggest factor in determining income inequality isn't whether you marry royalty, it’s simply whether someone is married at all.
