OP's comment still holds true: "Plenty of available jobs" is what happens when the deal you are offering- cash for labour- is not an acceptable deal to the labour side. When businesses cannot be profitable at market-chosen labour prices, the businesses will close down.
When low paid workers can't afford to live locally because of availability of affordable housing, they must live further away. Commuting has a cost too so if low paid workers can afford housing an hour away, it still might be cost prohibited to take those jobs because commuting costs too much (or "affordable" transportation isn't available). Then if you include the 2+ hours of commute time per shift to take those jobs, it may very well make those jobs less attractive as the effective hourly pay rate is lower than elsewhere.
