It becomes more understandable when you consider that “they” in terms of the capitalists aren’t a monolith, and though they all have the same broad goal of extracting as much value and profit as possible, each’s pursuit of that goal will inevitably bring them into conflict with each other as they all try to become the fattest pig. Gig companies don’t care if they’re hurting restaurants, it’s just business.
Yeah it also does in fact show what would happen if a good welfare system existed as a safety net for people. They would be bailing on the jobs knowing they had a safety net for a while. These extremely available gig jobs are literally performing the function of a safety net in this instance, in a fucked up way.
