And if you get sick, or you get in a car accident, or there's a fire in your apartment, or anything happens, and it's all over. the house of cards all falls down and you are left with nothing, but you can't think of that, because you are too busy trying to spend every waking moment to find a way out of the miserable job that is literally breaking your body in ways that will impact you for the rest of your life. And the real kicker? You consider yourself lucky. Because you had a friend a few months ago that got fired because of his drinking problem and now is homeless and has literally nothing, and you are so happy that you at least don't have that to deal with.
It may not be "compulsory" in that someone is holding a literal gun to their head, but it's compulsory in a lot of cases by the fact that the workers have literally no other choice. They can either stay at their job that is barely keeping them alive, or they can quit and lose what little they have (a roof over their heads, and food).
I was in that position, I ended up getting fired from that minimum wage job, and by sheer luck it was the same day I had gotten another job, i was going to start working 1st shift (overnights), and luckily they were okay with bumping up my hours to 30 so I could spend my now free days to look for a second job again. I eventually stumbled into a job that paid me $10 an hour to write html and style emails to match what a designer made, and I worked on that during my overnight job until I saved up enough money and vacation days to pivot from there into a job where I was paid about $15 an hour, and from there I was finally able to save a little and get out of the hell I was in.
I have my feelings about amazon, but I will say that for a lot of people I'm sure this raise is literally their savior. And anyone that is against this, especially because they feel amazon is doing it for the "wrong reasons", need to look at the positive impact this is going to have in these peoples lives. Because this is going to get a significant number of people back on their feet, and turn them from slaves just trying to survive, to productive members of society.
