Re: Efficient Market
If Uber ever made a profit, how hard would it be for someone with big pockets to shove them out of the market? They have software that is easily replicated, servers that can be rented from Amazon, drivers that will switch if you pay them a bit more, and customers who will switch if you charge them a bit less.
Apple, Google, Facebook etc can take them out in six months. But most likely there will never be any profit.
