No doubt that things are going to change...especially when you have both genders screaming for it, rather than just one. Both genders need to work to change the system...the change won't truly happen or be valuable unless everyone is involved.
Regarding the OP's original post, however, I think its somewhat irrational to assume that telling someone not to get married is going to work. People enter marriage with a very different mindset than the one presented here and rightfully so. More importantly, the limitations it puts on potential partners is unreasonable.
I definitely think there are things that can and should be done to mitigate the damage.
Understanding how equalization happens is important. So both partners going into the marriage making sure both of their assets are well documented. And then understanding how you're going to split equity in the event of a divorce so that you're contributing equally into the financial pot. For instance, you might really consider co-mingling things like inheritance funds that you acquire during marriage. You also might not be the only one contributing to household upgrades, etc. If you understand the rules, you at least do it with your eyes open and aren't shocked in the event of a divorce.
Making a list and understanding the "deal-breakers" in your relationship are important. Emotional deal-breakers (ie. infidelity) and financial ones (ie. one partner spending too much or not contributing)...so that you leave the marriage expeditiously and don't linger while things fester.
Before having kids...making a list of how you're going to split parental duties is important. You can make a marital parenting plan. That way, in the event of a split, you can easily show how you both co-parented together...even in marriage..and show an evaluator the breakdown in duties for each partner. It would greatly improve chances of shared custody/access.
Obviously making agreements for SS and CS won't work. But it doesn't mean it shouldn't be discussed. Not all litigants entering into divorce are unreasonable or cut-throat. I've heard of many, many people who are very fair and equitable in divorce situations. I think it truly helps when people have discussions about what might happen in a marital breakdown BEFORE marriage. It might not work out that way but the discussion is very important anyway.
In my opinion, I think its over-the-top to suggest you can't take some reasonable steps to improve your outcome in a divorce. And its also over-the-top to tell people not to marry...most are not going to take that advice.
