How are they slaves? They have the free will to decide if they want to work or not.
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.
Taking someone to task over the technically incorrect use of the word slavery seems a bit pedantic at best.
