Is no fault-divorce the real issue? I think the main problem is what is causing these divorces.

Too few children? Bigger families certainly divorce less.

Getting married too late? It does mean more sexual partners.

Birth control? Women on birth control have an increased preference for beta males.

I recall a guy mentioning years ago that if your woman isn't pregnant in her fertile years (because of "family planning"), she'll naturally have thoughts of finding someone that will, it's simple evolution.
