The only time I've seen this actually work is when the "rent" is set aside as savings. Especially for kids who are bad with money.

Seen it actually help a few friends who paid $500/month to their parents then got their 4 years rent paid back all at once when they moved out. It did help them with getting their own place and prevented them from spending that money on drugs, booze, and other things that you tend to spend money on when you're 18-25

No they don't. They don't appreciate the way that most of the world still works and most of the West worked even within the last 100 years, where inter-general families lived together and all contributed to support each other.

Boomers can be worse than that. Some of them (personal experience) even proudly announce that they are going to "live hard and leave nothing when they die." And expect to be congratulated for that.

My brother-in-law (who is Gen X) wanted to charge my nephew (his stepson) rent when my nephew graduated high school. My nephew's grandfather told my BIL "Nephew is whose name is on the house in the will. Yours is not." Also had to remind him his kids were probably taking up more resources since they were under 16 and not working.

Of course my BIL got married to my sister, had them move out to a farm, and got his name on her will instead of her other relatives, like her son. I didn't go to their wedding for other reasons, but the brainworms run deep among Mayonnaise-Americans.

Oh, my chud parents are fuuuuuuuuuuuuuucked.

At least from my anecdotal experience (lived at different times with separate parents and both sets of grandparents after turning 18) I think most people who would expect rent from their kids would be total scumbags and likely burger-brained.

The only one who asked for it, also conveniently kicked me out once for a short time on a misunderstanding (thought I was lying about having a job- or at least that's the claim, nowadays I don't know if that was just part of the plan- uh, typical narcissist stuff). They'd also always threaten to refuse the rent (and boot me out) if I didn't go to church, etc... and of course transitioning was a no-go. Talked to them about it much later (nowadays we're NC) and they said they had never even considered that it could be rental abuse... they're still a shithead but at least I don't think they're charging my siblings rent now

Amerikkkans cannot conceive of a mutually beneficial relationship except in the form of rent.

This sort of happened with two of my cousins -- when the older one turned 18, my aunt and uncle started charging her rent to continue living with them while she went to school. I'm not sure exactly what happened, but she ended up dropping out and getting married within a couple of years and has gone LC with them ever since. They did the same with the younger one, and she got all of the rent money back when she graduated and moved out. Now the older sister is pissed because they didn't do anything like that for her, and my uncle is insisting to everyone that it's "Trump derangement syndrome." He also thought it would be funny to use her Amazon account to buy a MAGA hat for her with her own credit card

Yeah, but parents that are themselves struggling don't typically go to the press to shame their children into paying up or moving out.

As always, this is going to heavily depend on the people and the circumstances. I don't think there's room for blanket assertions on what should be done.

I don't think there's anything wrong with asking to contribute to the household if they're able, I do think there's something wrong with saying "You have hit age you must pay me rent".

here's the thing, the parent is complaining about paying rent, not that they're child is sitting around doing nothing, that part you added yourself
