Edit: This was flippant because I was annoyed. There are a lot of people who work in well-paying jobs and have never really experienced what the labor that enables their relatively privileged lifestyle actually feels like. They often weigh in with "well, get a better job" but not only is that not an option for everyone, it means you're devaluing absolutely critical work. The snobbery among people who fail to see that is aggravating.
This future millionaire mindset, where you were "happy to have an income" because you anticipated better future returns, is ugly and detrimental to everyone around you. Every job that needs doing should be done for decent pay and with dignity, at a minimum.
?? Why would anyone work a crappy manual job if it weren't their only viable option?
Like, I'm sure there are exceptions but it seems unusual, since if you have better options, you'll pursue those instead.
First of all, comparatively Amazon warehouse work doesn't sound like "terrible working conditions", it sounds like a dream job, and it sounds like you have never really experienced typical manual labor if you describe it that way.
Second of all, was I exploited? What would that matter? Every other choice I had was worse or I would have taken one of them. Should the company have improved the working conditions? They did! They automated everything. All of the unskilled jobs are gone and the jobs that remain are higher paying mechanic or process operator jobs. Today I would have to take one of the worse choices.
