Uber's network of drivers is way of providing transportation services. This network doesn't just spring into existence. It must be created and it costs money. A traditional bus service also costs money; the buses must be purchased, the drivers hired and paid, the routes established and signs posted, etc. Why isn't a bus company unfairly competing with taxis by offering lower fares based on massive upfront investments in bigger vehicles that are paid back over many years? Uber's "bus" is its network.

There is no monopoly in transportation. People can drive their own cars, take buses, take taxies, ride Lyft, walk, bike, etc. Uber is creating a network.
> This not only discourages the competition, it discourages the existence of competition.
Discouraging competition is the same as discouraging the existence of competition.
To compete effectively against any good business requires investment. Uber is competing against the taxi network, bus services, zipcar, etc. Uber's strategy requires investment in building a network of drivers that can quickly reach anyone in the service area. To build this network, they have to invest in drivers and passengers. They do this by paying drivers more than they produce and offering passengers service for less than it costs. As more drivers and passengers join the network, costs come down, service gets better, prices may be able to be raised, and Uber may be able to recoup its investment and earn a profit. Maybe. if they earn too much of a profit by charging passengers too much or paying drivers too little, they risk being replaced by other app makers who offer Uber's network of drivers and passengers a better deal.
It's uncertain if Uber will be profitable. But in trying to be profitable, Uber is definitely offering drivers and passengers better options than what they already have (otherwise, the drivers and passengers would not be using Uber).
