There's good and bad to it. People like this need institutionalized care more often than not. Families can't always deal with it effectively. But the institutions themselves are also ripe for profiteering since a lot of people just want to get rid of their mentally ill relative and don't really give a shit about the conditions.

I become a bit of a pariah with some family when I tell them they can't humor the crazy people. Get accused of being an asshole which is true enough, but you give a mouse a cookie it's gonna want a glass of milk.
