If they worked for a decade and never got a pay rise (other than minimum wage increases), why are they still working there? In an ideal world, you get wage and career progression over time, or move on to a different career otherwise.
Folks rarely have this choice. What industry wants a barista outside food service? This is why we get stuck wearing a green apron for a decade, or working call center jobs, or any other crappy job.
People aren’t locked into being baristas. People immigrate from all over the world to the US, and become whatever they have to. Dry cleaners, landscapers, cooks, maids, nurses, etc.
