I provided two possible quotes. Ofc they need some working since I’m not good at that.

More possibilites:

If you get paid the same for working hard than the guy next to you that spends the whole working day staring at the phone, you’re not free

If your manager just “manages” you and gets paid double, you’re not free

If you have to stay the 8h even after your job is done, you’re not free

If you have to ask for permission to go to the doctor you’re not free

If you have to ask for permission to take your vacation days you’re not free

If your wage increases don’t even keep up with inflation, you’re not free

If your rent is more than 10% of your 40h/week wage, you’re not free
