We do the same, hubby gets his paid, mine comes out of his check. (His company has a whole lot more people, though.) Trust me, he'd rather pay it than not. If you like how it's worked for you, having the same level of service (and it IS a service) for your wife isn't a choice, it's necessary.
I've had folks pushing 400 pounds that tell me they can't afford insurance, and I tell them that they can't afford to NOT have it, for obvious reasons. (Once I explain how knees, hips, & ankles fail, not to mention how internal organs are dealing, they understand, but still want to live in "the world they're in".) Sigh.
