"I think many husbands would be happy to pay a little money (if they had any, after groceries) if it meant their wives would have a little energy left for *them*."
Safe to say! I pay for our full-time nanny, a housecleaner, and a yard guy. I'd much rather have pleasant time with my wife rather than hear moaning about her being tired.
Anyone who purchases a new car each year can do all of the above, too (simply by holding off on the car purchase).
We don't get a new car EVER, but we could re-prioritize to afford help, if it was truly important to us, and I expect many families could.
