> Please, define what is a poverty wage, it is important.
The ability to afford adequate housing, food, and clothing. I'm not saying we should mandate people can afford a 1500 sq. ft. home, ribeye steaks every evening, and Ralph Lauren Polo threads, but how about at least a one bedroom, one bathroom apartment; nutritious, nourishing food; Walmart clothing at a minimum.
> What is the change of the model in case of the restaurant?
Removing the "tipping" system. Increase prices such that an employee can afford the above mentioned necessities.
> I can see only one, automate the jobs away to reduce the costs, namely replace humans with robots.
I think the industry will go here no matter what changes we do or do not make to policy, business models, etc.
> But, if we consider these crappy jobs, what about people that are not qualified/able to do any more advanced jobs? People have vastly different cognitive abilities, it is not like we can teach everyone to code. It will not work.
We either decide these people are expendable, or that they are human beings worthy of a baseline of a dignified life. I define a dignified life as the ability to have at least the minimums I described above.
