Why should a man be able to dump his wife

.... not even gonna finish the whole thing- as if it's the men who initiate most divorce...

Heap fallacy

Fallacy doesn't mean it's wrong. I don't mean you wouldn't be able to do it accurately, I mean you shouldn't put a number on it at all. It's not a paid position or something requiring reimbursement. It's like billing your friend for a favour that didn't financially cost anything- you could put a number on it, but you shouldn't.

sacrificed work experience

That's your opinion. You've artificially deemed it a "sacrifice" instead of a choice. If she chooses to take a lower-paying job, is she entitled to the pay from her old job? No, that's dumb, and so is alimony. Divorcing is like quitting or getting fired- you don't get to keep a salary afterwards.

benefited the man

This isn't a 1-way street. The woman benefits too. Many would say the woman benefits more by not having to remain a corporate drone to put food on the table. You view marriage like a sacrifice of the woman that only benefits the man- I won't be able to make a convincing argument otherwise until you see marriage as equal partnership of 2 mutually consenting adults instead of "man inflicts spousal contract on woman".

She gets the earnings that expanded in the time that they were married, and debts acquired during the marriage, not pre-existing property or debts

Bull. Never heard of a woman having to pay after the man gets down on his luck.

Never said I supported that

That's what alimony is. Otherwise, why is alimony tied to the man's income?
