If we still made and sold shirts made using Medieval-level technology, a single one would cost around $5,000 if the spinners and weavers made only the US federal minimum wage of $7.25 an hour.

Yes, those Middle Ages shirts would be higher quality. Not enormously so, but they were designed to last for obvious reasons.

Automation and technology can now create a shirt that costs ~$25. No matter what degrowther nonsense you believe, that’s amazing.
