If I knew how to answer questions like that, you'd see me on TV giving interviews about my trillion-dollar hedge fund.

I have yet to see a single scenario where this actually happened without being a product of government-granted monopoly (e.g. patents in pharma). But if Uber is going to charge me 3x for the same ride (just as taxis do now) I'll stop using them (just as I stopped using taxis). In the meantime, I've been saving money for a decade. I think it's a good deal.
