No, I don't think it's a pipe dream. It already exists. It's just that people don't take advantage of it.
High divorce rates have been the news for a long time. Like smoking or drugs, there's no one alive in the United States now, that could get married, that doesn't know of this problem. There are many, many religious institutions that would be glad to offer advice, counseling, etc. Mostly for free (or, certainly, for less than the cost of a divorce ten years later). There are psychologists/therapists that can help a couple determine compatibility. There are weekend seminars on how to do it correctly. There are whole sections of libraries and book stores, internet sites, etc., that are filled with sage advice.
I don't want the federal or state government offering it's help. Anti-religious zealots would take out the bulk of the realistic help. Auditing programs would begin.... the slope of problems is endless.
What we need are parents - single or divorced or together or whatever - to help teach their kids that seeking advice is worthwhile. That their offspring will be responsible for their decision. That their offspring's offspring will bear the result of that decision, and any to follow.
Parents need help. I agree. I think we need to stop buying any magazine that has Britney's current collapse, or Lohan's current jail time, or any of that crap on it. That won't happen, but it should. I don't think that should become law (that pesky first amendment), but we consumers can stop it.
Personal responsibility. We're getting exactly what we're asking for.
