There are so many people out there who do not know how to take care of themselves. I never claimed to be the cleanest person in the world, but at least I can ensure my apartment is tidy without someone else doing the work for me. When I went to college, I couldn't tell you how many people did not know how to use a standard washer and dryer set at 18 or 19 years old. It's maddening.
If somebody doesn't know how to take care of themselves by the time they're in their early 20s, they probably won't figure it out unless a rude awakening comes their way. One couple is dealing with said awakening because they can no longer afford their housekeeper. Well, the husband could technically afford it, but he made it very clear early on in their marriage that his wife had to pay for the service because she wanted it.
