I started reading this thinking I would disagree, but you're right, in some countries (Canada for sure), there's a weird thing that some genders are more equal than others. I know this sounds bad, but I am a left-leaning feminist.
I've seen first hand where spouses of equal education and opportunity are treated as traditional values applied.
And nearly always it's the male that has to take a second job/cash in their retirement to meet societies demands.
I went through a divorce in Canada, there is a thing called "amiable divorce/separation". Where both parties negotiate a fair divorce agreement rather than the standard "Pay continued support for X months/years + lump sum".
So there is some variability, and of course in my case it was a "happy path" scenario where both me and my ex-wife mutually wanted the divorce.
But by default you have to pay spousal support regardless of how well-off your partner is. The assumption is that women will be worse off after a divorce financially. Which is really not a contemporary point of view to make as a blanket statement.
