Marriage isn't the problem, it's the lack of high quality women to marry. The ones who wants to be caring wives, caring mothers, supportive etc etc
First, i would recommend to men to still looksmaxx, even during the marriage, in case of a divorce/affair, because you will still date after one, soo. Women do it already.
Second, you need to work, place your money wisely (go frugal) and if possible buy lands and own your house before signing any contract.
For example i own lands and be the sole owner of my grandparents house, so if MrsTony decide to divorce she can't get the house. But in that case, i will make a testament for her and our biological kids will inherit the house tax-free, so they'll have a home, in case i die early (i'm a firefighter).
3rd, get a prenup. In the next 10-15 years, women will work and earn as much than men (If AI doesn't do any further damage but i've a doubt), if not more, and will get prenups because a lot of them doesn't like their own medecine, especially face to the divorce court.
4th, find a girl who has everything : independent, have money, pay the bills, can finance her lifestyle etc, so if she still decide to follow you, be loyal and carrying your offsprings, it means she genuinely loves you and is attracted to you. This is the key.
We don't need women relying on our money and just barely tolerate us just because we pay her bills, fuck that bs ngl
