orcishgamer: It sounds like the reality was she was cleaning up after herself and barely at that. I suspect she just exaggerated the whole cleaning up after everyone thing. If she was really poor little Cinderella the family wouldn't have had a services trade with the gal who came in and cleaned.
I'm not sure, but it's possible. Demanding that a "cleaning lady" does jobs is out of line in any case as long as she doesn't pay for said cleaning lady herself, or at least contributes to it.
orcishgamer: You don't get some sort of special reward for cleaning up after yourself, that's what you do, tough shit, it's life.
The problem is that once the situation has worsened to a point as the one we see in the video, the above assessment - as justified as it may be - is unlikely to solve the problem. The daughter seems unwilling to do basic chores, the dad tries to force her by punishing her if she doesn't do them. Increasing the punishment will only worsen the situation. Offering her rewards for "correct" behavior is, however, likely to improve it.
I know that that feels somewhat awkward because, in a way, it rewards the kid for not having done things that should go without saying. (It's especially awkward when there are siblings around who didn't have these problems, but that's usually solvable too.) But it's very often the best solution to get back to a working relationship, upon which the family can build later.
You can of course say "the kid is just a brat" - it might be justified (depending on the assumptions we make), but it won't do anything to improve the situation. (Plus, the brattiness might have roots in earlier parenting mistakes, which would increase the dad's responsibility for finding a working solution.)
