Let's not pat ourselves on the back too much regarding what wonderful parents we are- one third of all babies are born out of wedlock, and that is largely from Gen Xers and older Gen Yers. Divorce and abortion rates may have started to level off and decline in our generation, but our ancestors would still be shocked at the sexual immorality that we take for granted.
Which 'moral' ancestors? The ones who originated common-law marriage? The ones who practiced 'free love' in the 20s and 60s? 8^)
No, I agree that returing to a perception of immorality to shame parents against raising bastard kids is important, that a stable marriage providing good role models for both boys and girls is important, and a legal marriage is usually the most stable you can get, but I don't think it's the first problem with Gen X parents that should be tackled. It certainly doesn't have a huge effect why I'm happy about Gen X parenting when viewed comparably with Boomers, though I'd be interested to see how the divorce rates compare between Gen X and Boomers when it comes to divorce rates with and without kids.
That first problem? Making it easier for one parent to parent full time by lowering taxes back to pre WWII levels, and cutting government back to constitutional levels so people can go about their business without paying for a lawyer every day of their lives.
