What we really need is more privately-sponsored and available pre-marital education -- from churches and synagogues especially. We need couples mentoring within congregations by older, successful married people to newlyweds and new parents. We need more research and development into compatibility screening methods. It's not enough to try to close the barn door. I am also in favor of parental licensing. Children would not be illegitimate, but their parents could be.
True. But we also need to make it more difficult to get a divorce. You shouldn't be able legally to divorce becasue you're unfulfilled. Some circumstances cal.l for it, but we've made it entirely too much a convenience. The first "grounds" we should wipe off the books is "irreconcilable differences." It's a meaningless term.
At the very least, couples should be required to go through a counseling program such as the one you described before they can divorce for anything other than abuse, addiction, or adultery.
