Third-world immigration solves this problem. When your housekeeper is a peasant from Honduras, there’s no reason to feel bad about it. You don’t have to wonder about the details of her life outside of work. You can barely communicate with her. She may be cleaning your floors for minimum wage (or less) while your children travel abroad, but you’re not exploiting her. Just the opposite. You’re giving her a hand up, allowing her to participate in the American dream.
