There are no minimum wage jobs where I live anymore, and I live in a lower cost of living area (not Manhattan or silicon valley, LOL). I'm not surprised no one can afford rent at $7/hr when no one can find a job paying $7/hr. Costco has a sign up paying $19/hr to empty trash cans and they can't hire people at that low of pay and the article claims its a tragedy that a middle tier single bedroom would take $21 as a nationwide average; although I live in a lower cost of living area.
The government "Fair Market Rent" is sort of median quality housing. If the goal is to demand that even people at the literal bottom of the barrel of income in the 0-th percentile live in 50th percentile housing, then who will live in the 0th to 50th percentile of housing. A goal of having the lowest percentile in any group meet median achievements is inherently impossible.
There does not seem to be any actionable plan proposed; to me its obvious that raising the legal minimum wage from $7 to perhaps $8 will not improve anything if the absolute bottom of the barrel of jobs in low paying areas is already $19/hr AND there is no supply so there are unfilled jobs. Another obvious proposal is building more housing to crash the price, and the ownership class is not going to tolerate that behavior LOL.
As a thought experiment, if the living conditions are indeed unlivable as the guilt inducing article proposes, fine, lets run with that theory that its true nobody can live that way, then how are so many people living that way?
