I’m not assuming anything. It’s a job market. Like all markets they operate on supply and demand.

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.
