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?"
