There's nothing special required to open a restaurant in Sweden, which I think most would agree is a developed country. You need a business license and a food license (unsure how to translate), neither of which requires an education or training, and you need a proper location for preparing and serving food. Employees can be literally anyone off the street. You have to pass health inspections, but the inspectors don't care much about details if nothing dangerous is going on.

I personally appreciate your example of chef and had to delete the rest of what I had to say because it got way too emotional. It's a frustrating situation when you're making people happy by providing a service and still not being rewarded because capitalism.
