I googled this so this can be a discussion with a foundation.
"The expense of creating a food delivery app like DoorDash can range from $10,000 and $70,000. The costs and the final cost are based on several factors, such as the number of features available, the quality of the app, as well as demands of the marketplace, and even the business needs".
If this is indeed true, and the delivery app creator owns 0 cars and have 0 need to pay rent for their business.  Why won't they pay the drivers more since their overhead is so low?  They actually can make money while working another job.
