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.
You're not wrong.
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.
