In China it's a matter of politics rather than financial sense, of unifying the country hence why they have them in ethnic minority areas too. The trains would be like roads, sure, most people wouldn't take them from one end to the other, A to Z, but there are enough people to take them from A to D, J to N, Q to T, so to speak. If one could commute in one hour from Boston to DC for example each way, daily without flying, it opens up more economic opportunities in total. But like PG said, the competition to an airline isn't a car or a plane, it's Zoom.
