What if it's just to find the most desperate worker for the lowest pay possible?
In your example, so what if they give the job to the most desperate worker instead of a different one at a higher price? Are we supposed to prefer that the desperate worker does not get the job and instead it goes to someone else at a higher rate?
If someone is desperate for a job because they really need work, I’d prefer that a platform help them get matched with jobs. Wouldn’t you? I think you’re so focused on penalizing corporations that you’re missing the obvious.
