As a product of a broken home, I experienced first hand the very simple and straight forward difficulties regarding broken homes.  Mine was a fairly ideal situation as far as such things go, but there was very real jealousy and resentment from both my biological and step parents alike as my very existence complicated their lives.  I have met folks with much worse experiences as well.

I'm surprised that more people from my generation are not more concerned about this sort of thing.

When birth control began to allow people to have sex without children, people began to push back marriage to their 20's for economic reasons, and economics is driving the breakdown of traditional marriage.  If you'll recall your history (or even literature), "kids" were getting married in their teens. That's because they are not kids folks, however much you may like to think of them as such. Expecting people to abstain from sex for a decade or more after hitting puberty is unrealistic, and indeed cruel.

Furthermore, I believe the emotional state of young men and women is such that they are much more susceptible to falling in love to a depth that motivates lifelong commitment.  It is easy to point at failed marriages of the young and state that this is not true, but are those failures not more the result of a lack of opportunity for our young men and women just starting out?  Don't you remember how very strong the feelings were at that age, and how you felt you wanted to be with someone forever?  In the past, once these feelings were allowed to consummate themselves, we held them accountable for the promises they made, and we had a place for them in society so that they could support the family.  This is the model for making families actually work.

You won't find many supporters of going back to early marriages, high wage entry level jobs, and penalties for out of wedlock sex though.  As far as conservatives are concerned, it seems if you don't go $40k+ in debt and finish college, you deserve a go nowhere, dead end, low wage job for life.  Half of all wage earners in America as of our last census made $20,000 or less, yet conservatives act as if the fix is just to chastise people more severely for making relatively minor mistakes.

Oh my goodness, Billy and Suzy are 18 and having sex?!

Folks...?  this aint cuttin' it.
