This is something that actually gets under my skin for some reason, it mostly seems to be an American thing.
Here is a typical comment from an American on a forum out here:
My wife has been a good partner and I have rewarded her appropriately.
Following that I added a comment about how much salary he gives her as a bit of a dig to which he didn't even react. He sees nothing wrong with it, he actually pays his wife a set amount each month that she is 'allowed' to spend on herself.
I can't see myself being in a relationship where 'love' was quantified and if my misses lacked enough dignity to allow me to treat her as an employee, then she wouldn't be my wife. I can understand when people may give 'house-keeping' to housewives, but that is more budgeting though I think.
What would the girls on her think about being "appropriately rewarded" for being a good partner?
