The premise is good on paper, but not much in reality.
So many in this area are income restricted.
For 2 people here, the cut-off is $38,580 a year.
The min wage currently is $13/Hr (IL)
That's 2,967 hours two people can work, or 1,483 hours per person.
Which is 28.5 hours a week…at min wage.
You almost have to be poor on purpose.
If someone works full time, at minimum wage, the other person could only work 17 hours a week, and most places wouldn't even bother hiring someone for such few hours.
