A chef's pay is a function of the market, and that's why everybody is exiting the industry right now. Head chefs and restaurant owners are used to decades of low wages and think it's quite insulting that anybody would dare ask for a better wage. Then they wonder why "nobody wants to work anymore". At the same time, chances of advancing your career are very limited. If you manage to stick around for a few years as a chef, you will already be able to manage your own restaurant, but the salary for that will be just marginally higher. Unless you want to strike it out on your own, and take on massive debt for a business with low margins.
Working in a kitchen is the worst career choice a young person can make. If you have that skill, ambition, passion and drive, you will be much better rewarded in any other sector.
