To your point about the real business model of companies like Uber, coincidentally, a few days ago I published this article about Uber: A Better Name For The So-Called “Sharing Economy” Is “The Shareworker Economy” A Shareworker Is Nothing More Than An Old-Time Sharecropper In Fancy New Clothes.
If you use accepted per-mile numbers for the cost of ownership and operation of a vehicle, Uber drivers earn less than the California minimum wage and also no overtime, no sick leave, no medical care, and no coverage for on-the-job injuries. Hard to see the value of this business model to anyone except Uber itself, which is still losing billions every year.
