Do people that have house cleaners have them because they are too lazy, or because they don’t have time to clean their homes themselves?

It used to be that to have a housekeeper (PC “house cleaner”) meant that you had means and did not want to spend time cleaning your own home. These days, with monstrous commutes and people working so much overtime on their job ([J]ust [O]ver [B]roke [S]yndrome), they don’t have time to clean their own place; even if they wanted to. Today, if one wants to have a clean home and hires a house cleaner, is it because they don’t want to take up their free time to do it, or there is simply not enough time for them to do it effectively?
