I'm not sure what it means for the people. In one way, fast food is the only obvious work available for them. That's the only reason they do it, nobody likes it otherwise. But on the other hand, perhaps it's only the most obvious choice available. Perhaps more drastic choices, perhaps involving moving to new cities, would become more attractive and hopefully get them out of wage slavery.
I'm grasping at straws. This is probably going to be bad for them.
