I agree that we in most of the western world generally are awash in things and that we all are "ungrateful bastards" (wording mine).
But then the author goes on about how time it would take to make a shirt in the medieval age and then calculates the cost using today's minimum wage. That make no sense at all, and dies give us any information.
Maybe compare it to price of a loaf of bread back then, that would give us an idea. Then we'd have singing to go by.
Loaf of bread? Grind the wheat using a hand mill or mortar/pestle, mix ingredients, knead, rise, bake. Doing it all low tech, takes about two hours of work: price at least $14.50 per loaf on labor alone.
It's not really possible to compare prices across such large time periods. The author chose to fix the price of one commodity (unskilled labor), while you chose a difference commodity (food).
