> Yet the workers all chose to work there, implying it was better than the next best option available to them.
That's not how minimum-wage labor effectively works. The workers (many of whom have just entered the workforce, myself included at the time) apply for all the available jobs in their area and hope that at least one hires them.
At that level, the employers are in a race to the bottom, and rather than attempting to be a better choice to attract and support their labor force, their reliance on the workers' desperation means they all push the limits to see how much they can get out of workers for how little in return. It's the entire reason we even have minimum wage laws.
And they all do it. There's nothing particularly noteworthy about any given employer. I saw the same behavior, through my siblings' experience, at four different mega-franchisers.
> For the employees, they are better off for that employer offering the employment, than not doing so.
So, no. The employees aren't any better off being exploited by any given employer, when their only other choice is unemployment or identical exploitation by another employer.
