I'm glad it works for them. But personally, marriage that is fundamentally unequal (where one partner gets punished in ways that the other does not) would not work for me.

I can see how it would work for some personality types and also for people who have habits they want help breaking, for example an addict who wants to get clean, could maybe engage in this kind of dynamic. It could work for being a shopaholic too, to have an "allowance" that limits spending.
