Absent coercion, I'd assume that was that person's free choice and that taking whatever state subsidy was implied plug $40/week is better than just the state subsidy.
(Work provides a way to fill the time, have social interactions, and a sense of purpose and accomplishment, in addition to the financial aspect.)
See my other comment - if you want to transfer wealth to the poor you can do this with EITC or other programs that don't discourage work. A job guarantee is my preferred policy.
(And keep the borders closed - poor brown people don't even count for 3/5.)
Also, you seem to be imagining that if landlords of poor people would rather get $0/month in rent (with houses going vacant) than reduce rents. When did landlords become so non-greedy?
