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.
But again, it seems weird when a male has to work 2 jobs in their 50's to send large monthly payments to a female that has a larger or equivalent net worth.
And it happens routinely. Of course, there are also a lot of men out there that just want to stiff their ex. But that doesn't mean my former example isn't happening.
And this was exactly what happened to my friends. The women who sought alimony actually earned much more. The financial burden was so tough that it turned a good hard working member of the society into almost a criminal (if you don't pay alimony, you can be even arrested for it in some countries).
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.
