Most people couldn't care less how much the restaurant or the the driver is making from an order. Believing the market will regulate itself to a point where the restaurant and the driver receive a fair cut while the customer pays less and the gig app makes a profit is almost childish. The scales are not balanced in this equation. A company that has virtually infinite money to burn is in a position to burn the whole market to the ground and rebuild it on it's own terms if it wished. And in fact that's what has been happening.
