>It's hard to imagine expenses adding up anywhere close to $58/day Well thankfully we don't have to imagine, people have researched this: https://livingwage.mit.edu/ . According to these data, the living wage across the US in 2019 was $16.54: https://livingwage.mit.edu/articles/61-new-living-wage-data-... . So it's not at all inconceivable that the federal minimum is a poverty wage, in fact it almost certainly is.
But that has nothing to do with GP's claim? GP was talking about your "net pay is below zero", meaning that the job itself pays negative. eg. you get paid $50/day but spent $55/day to earn it. Your comment seems to be about the minimum wage not being able to sustain a given living standard, eg. you get paid $50/day but you need to spend $55/day to survive.
Second, it's not really "per day", that's an average. Most bills recur monthly. Assuming a month of four weeks, and working 5 days per week, that's 20 * $50 = $1000 per month. Doesn't that seem like an extremely low number to pay for rent, transportation, food, health care, kids, utilities, etc? I pay more for that in rent every month.
