“… but it's expensive due to the drivers.“

Really? Drivers only get paid 2 to 3 dollars per delivery from DoorDash and UberEats. These companies are predatory and pay the drivers less than it cost the drivers to deliver. So now these companies will assume all the costs instead of passing the cost down to the drivers? How does that make them more profitable? Maybe there’s some DoorDash or Uber eaters here that can explain my confusion.
