You think running an Uber competitor is easier than running an airline? I've got a great investment for you...

If a barrier to entry is just financial, it's no barrier at all.

Let's think through the dynamics of the situation you describe. You say Uber is doomed because competition is too fierce. Yet you say the competitors are also doomed. Somebody will go bankrupt first. That will reduce competition and profits will go up. Maybe another competitor shows up and it's back to doomed. But then they go out of business, too. Eventually, people will stop entering this doomed industry and if Uber is still around, it'll start turning a profit. Every industry goes through times of competition and times of consolidation.
