Who has more than one job to survive?

I asked another question here and someone answered that "side hustle" is a cute way to say when people have two or three jobs to survive. I don't believe you should use the term "side hustle" or side kick business when you have more than a job to survive. These terms should only be reflected upon those who has a normal one-type job with decent or well-paid salary and feels to earn some more to go towards holidays, shopping or just making living conditions better than average. Which brings me to wondering how many else has more than a job to survive?
