This seems like an unreasonably high standard for a single minimum wage income unless they're using the excess here as a proxy for other necessities.
Edit: This seems unreasonably high because it greatly exceeds the standard of living we expect for a single minimum wage income household. Sure it would be nice if a single minimum wage household could rend a 2br but that's not what we currently expect them to be able to do. Saying "people who make X can't afford Y" when we didn't expect them to afford Y in the first place isn't very meaningful when you're discussing the ability of people making X to have a standard of living that meets our expectations for people making X.
