Rather than just help them (which is cheaper btw) they take services away from everyone in an attempt to make their area shitty enough they'll go somewhere else...
Completely ignoring that they're making it shitty for the people they want to keep too, which makes people want to leave and depressed selling prices, which can easily lead to a panic and flight from an area destroying the community.
Even from a purely selfish capitalistic perspective, it's best to just have a fucking safety net. Beyond all the ethical reasons we should, there's not a single logical reason not to fucking help people.
