Fair response, appreciate your thoughtfulness. Your point about lack of advancement is compelling.
Doctors, financiers, etc prove that people are willing to go through life phases that tear them down mentally and physically (could easily argue that for them it can be worse than "peeing in a bottle"), but you're right, they'll all justify it saying "it won't be like this 5 years from now".
I'm curious as to how Amazon would respond to a question like, "what opportunities for advancement do your lower level workers have?"
I know they offer advancement programs like this one: https://www.aboutamazon.com/working-at-amazon/career-choice
Where they pay for your tuition.
these Amazon warehouse jobs don't lead to being a millionaire. they don't even lead to a decent career. i doubt you could even get promoted to Amazon low-level management out of one of these jobs. it is pure exploitation.
