If people want to eat and make rent, they need to afford it somehow, and the employment options are bleak (see: charging scooters).
So maybe you meant they have "the free will to decide if they want to work shitty jobs, or not live". We can't be too surprised that the suicide rate is going up in this country.
That’s a weird definition of a slave and free will. By this definition none of us have free will since most things we do are driven by some motivation. I want to eat and make rent, so I work for the money to do so. Now I’m a slave?
Income inequality, underemployment and lack of employment opportunities are real problems. But words have meaning, and we as a species have had a pretty ugly history with slavery. Let’s not dilute the meaning of that word when there are others that are more accurate.
Experience demonstrates that there may be a slavery of wages only a little less galling and crushing in its effects than chattel slavery, and this slavery of wages must go down with the other.
If you hate your job, which has negative affects on your health, are you really free just because you get to choose what clothes you wear or what you have for lunch?
