Why not? I don't know the exact numbers involved, but if, for the sake of argument, the maid has 30 clients and a maid service costs $100 per month, the maid would make $3000 a month before taxes etc. Surely there's at least a possibility that the rest of his or her expenses are low enough that they can afford a $100 maid service of their own. Especially if they are living with someone and can divide the living expenses.
OK, try to answer this question for yourself. Let's say you make 50$/hour from you daily job reinstalling Windows. Would you pay somebody to do it for you on your home pc at 50$/hour rate?
