I would prefer to live in the US than any of these countries funding HSR. Electric cars and electric scooters are enough to get around the city and around the state, with flights for anything much longer than that. Autonomous vehicles available via subscription will make that even better.
The United States can be one of these countries funding HSR. Countries that are quite pleasant to live in--and some that aren't, depending on your outlook--are already funding HSR and already have expansive rail networks. There's no reason we can't, too.
