"Alienation of the worker from other workers"

Now, look at the 'gig economy'. Instead of grousing about shitty bosses, these companies pit 'employee' against each other. The gig economy companies are setting up zero sum style games: There's only X work per day, and each person claws for their slice of it against others.
