No fault divorce has had terrible consequences but you can't put the genie back in the bottle. What you can do though is modify divorce and child custody laws though.
For instance, if either partner wants a divorce but has no cause or "fault" (abuse, infidelity, etc) then they should should be able to divorce but not be treated as an equal in the settlement. That would do wonders with the Suburban wife who "falls out of love" with her husband in her 30s and gets the house and the car and much of the savings to go with a favorable child care arrangement. I know so many men that have been absolutely destroyed by women who they gave everything to and were faithful husbands and good fathers and the wife just decided she "wasn't getting her emotional needs met" or something else. She gets to keep living the life and start dating again while he now has to pay for her life and his and the kids while trying to rebuild everything when he didn't break any marriage vows. Had a friend recently go through this and she waited until right after he sold his business and crushed him. He ended up in an apartment and she got the house and the lions share of everything and was partying it up on his money. Saddest thing was he didn't care about the money, he would have gladly done anything to keep her but she "just didn't think he understood her needs" as she drove her Mercedes convertible and kept the condo in Breckinridge and picked up a new boyfriend in no time. Oh, and the kids had a rough go of it to and had trouble connecting with Dad in his small apartment in the little time he got them. The biggest nail to me was she used the fact he had been working insane hours for the last couple years trying to sell the company so they could spend more time together and have financial security against him, she filed within a few weeks of the deal closing and he had made millions. To be fair she had a "job" even though he brought in 90% of the income. So many stories like this.
If a woman wants to walk on a marriage without cause she shouldn't be able to take the man to the cleaners, she should be able to leave but leave without much and be treated as the one who broke the contract and suffer the penalty for that. If she leaves without cause then the husband should get first right of refusal on just about everything from the house to the cars to the child care arrangement. Do that and a lot more of those women will work a LOT harder at their marriages and realize it is a partnership. Most of marital laws have shifted to favor the wife without any adjustment.
Oh, and no doubt there are men that act like scum as well but typically the men are doing something that is cause (abuse, infidelity, etc.). If that happens they should also be treated harshly in the divorce. Men are certainly capable of being terrible husbands and fathers and generally horrible humans.
You should be able to get your freedom without cause but it should come at a price unless both parties agree it just isn't working. They should of course be able to settle how they wish. It's just you can't have one party incentivized to break a contract and many marriages are set up that way. It should always be strongly discouraged from breaking up a contract or in this case a marriage and the one who breaks it or causes the break has to face consequences for doing so.
Or we just keep doing the things the way we are and fewer and fewer people will get married and have kids. I've been married 29 years and the only way we have made it is both my wife and I have never considered divorce an option. We have had our hard times for sure as all couples do, it's not all a fairy tale. If you make divorce an easy and acceptable option though people will use that option far more often and that is the environment we have encouraged.
