You may think a wife is a civvie, but it's probably one of the world's most expensive providers.
If I wanted someone to cook and clean, I'd hire a maid.
If I didn't take care of her financial needs when they arise, she'd eventually leave or become non-exclusive. You can only take starvation dire poverty so long especially if you are somewhat attractive.
It's the company, sex and her time that I want most and I spend a fortune on her. Now please explain how that is a civvie?
Perhaps more exclusive? (at least I hope so!)
