There's a long tradition of conspiracy theorizing around Shakespeare, that he didn't actually write his own plays, that they were instead written by Francis Bacon or Queen Elizabeth or something ridiculous. These arguments usually start from his background: how could the son of a common glovemaker have gotten the sort of education necessary to write like this?

The thing is, glovemaker was a highly skilled profession. Exactly like you said, any dum dum could cut a hole in a sheet of fabric and call it a poncho, but handmade shoes and gloves take serious craftsmanship. This kind of profession would have put Shakespeare's family firmly in the upper-middle class.

Stuff done "at home" obviously involves work, but it wasn't a "profession" in a notional sense so it wasn't recorded. Certainly we should assume that there was trade within and between cities based on this kind of output too (i.e. "Is that one of Marie's sweaters?", "Here's a few coins, go to Sophie down the street and see if she has any more of that jam from last summer").

I know almost nothing about medieval France, but perhaps peasants from smaller surrounding cities may have come to this one to learn or work, leading to this skew?
