What if some people do not fit into some pre-made construction of how some dictator imagines a “nice living situation”? Every person is an individual with individual needs. Presuming, that a single bedroom is big or small enough for every single person is absolutely undermining the fact of how diverse people actually are, as are their visions of their own lives.
If there are ten people with ten different expectations, they would all vote for something, in summary/conclusion, “in the middle”, which would make nobody happy. The best would be, if everyone could choose for themselves and that is the case right now, except many people perhaps cannot afford, what they’d wish for. Still, better than having a “democracy”, where nobody is truly happy.
