In my area it's like they want you to be poor. Those legitimately posted listings in my area are exclusively "scams", in that they will technically hire some people through those listings, but in reality they're just hiring immigrant labour for pennies on the dollar, and using state-funded labour agencies to promote these jobs which objectively could not support American citizens. I've seen one listing that said they wanted harvesters for crops, they were paying by the amount picked, not an hourly wage. This is a classic scam where you end up getting less than minimum wage, and the Federal government has to step in after the fact to get you up to the disgustingly low minimum wage to make up for that discrepancy.
