It is "fine" actually, because if your UBI competes favourably with the wages you'd otherwise pay, those tiny wages are in some sense risk mitigation. You bank margin so you can ride out when the work or workers evaporate temporarily, then someone sinks the expense when you eventually need to pay or charge more, and it's probably not them because they can't afford roofs in the first place.

My politics have nothing to do with it. I know roofers, roofing company owners, general contractors, construction workers, and others. I am a contractor, and I'm struggling. It's fine
