> There is no need to make a freaking model out of something so obvious. But consider that almost the entire first half of the Das Kapital's first volume is precisely a (very tedious) formulation of precisely this: "workers produce more than they get to consume, that's how non-workers can be sustained". And you can find there the criticism of other contemporary economic theorists who apparently disagreed with that ("nah, the workers spend, like, 8 hours of work just to make up for the materials that's consumed in the manufacturing process, so the actual profit is made only when they work the 9th and later hours so if the work day would be restricted to 8 hours then all the factories will go bust; would someone please think of the entrepreneurs!").
