The real solution is to make marriage illegal

How so? In countries such as Australia and the UK, even living together for 2 years means being treated, upon separation, as though you were married. That means the man still loses half of everything (allegedly half - more like 80% +).

Marriage is nothing more than a piece of paper. Pre-nups should be compulsory. If a couple get divorced then each person should be entitled to 50% of everything they gained during their time together. They should not have to lose half of what they had when they entered the marriage. It's really quite simple, IMHO.

That said, how 'workable' it is remains to be seen.
