I think for most people the point of living with parents (or in-laws, as happened to me) was that you can’t afford to live somewhere on your own, so paying rent to them is just extending the amount of time you end up living with them. For the most part, that money is better spent paying off debt, or saving up to live on your own. My husband and I lived with his parents while we saved to buy our own place. We paid them a few hundred every month, but it in no way was like real “rent” money. I think the thing that is annoying about a lot of those who are quoted here is that they are super ungrateful for what’s being done for them.
