Suppose you run a restaurant in the region of North Central Alpine Austria. You have a well regarded — and well payed — head chef who runs the place.
However for traditional reasons rooted in how people viewed social class 150 years ago, you can’t pay anyone else at the restaurant a salary. The other employees learn valuable skills as they try to get good enough to move up to the Northern Forest Lands, where they can be paid directly. You can give them free food, lodging, post-secondary education vouchers, and other perks, but only that manner of in-kind compensation is allowed by the region’s restaurant commission.
