I don't know that Uber turning a mere 14 years old is proof that the market economy isn't functioning. In a time of incredibly low interest rates and the resulting free-flowing money sloshing around looking for any possible return, I'd expect a lot of companies to reach their teens without that being proof that they can continue indefinitely without showing profits and returns to investors.
