The OP seems to be mixing his fantasy of wasting billions upon billions for nothing with his general hatred of the United States.
I love this country.
Don't put words in my mouth Dickhead.
You cannot love this country and advocate for wasting hundreds of billions of dollars on a system that would need hundreds of billions of dollars to run the system.
^^Another nut putting words in my mouth.
Pretty tough to have a normal discussion around here.
Specifically, what words did I put in your mouth?
There is one corridor in the United States where a high-speed rail can be profitable. That would be the NE corridor which has 41 MILLION people. No other proposed high-speed railway has anything even in the ballpark with that number. Without that number of potential riders, they make no sense whatsoever.
There are a few, but that number is shrinking every year.
One of the original proposals 40 years ago was for one to run from LA to Las Vegas. That one was actually far along in the planning, with construction due to start at almost any time. But ultimately, it was cancelled because some screamed it would kill turtles. And in the decades since, the explosion of Indian Casinos in California has made the plan outdated anyways. Nowhere near as many go to Vegas anymore from LA, as there are casinos all over California, and the explosion in Prim.
I still remember when that town was literally a gas station, a small motel, and a casino not much bigger than a convenience store.
There was also a plan for one to run from San Diego to LA, but that was also scrapped as the cost of land became excessive. What in 1980 involved mostly buying up farmland by 2010 would have become buying up housing developments so it was cancelled.
But the only other one that could have (and almost was) made was the upgrading of the Capitol Corridor. A 170 mile route from Sacramento to San Francisco, that one was actually about to start construction. At the time of COVID, the route was expected to pass over 2 million riders a year, so that stretch would have been an anchor to build the rest of a bullet train system off of.
But the Governor cancelled the project, as he had his own idea for a bullet train in California. And it involved going from LA to San Francisco, not from Sacramento. That is why they have sunk over $100 billion into a train that will never be completed, and they have not even figured out how to get it to LA.
The US is simply a poor choice for any kind of National High Speed rail. The cities are too far apart, to dense, and to large. Add in we already have a great Interstate Highway system and the large percentage that own cars, it is simply not needed. Myself, I would love to see them used for an upgrade to some of the commuter rail systems in the country. But out of the 4 most used ones in the country, only a single one could really use such a train.
The Boston-NY-DC-Philly region is simply so congested that clearing the required right of way would be impossible. In Los Angeles they could eliminate some of that for some lines, but then you have the entire issue of topography. Most of those trains do not even hit their top speed as it is, because of terrain. The only one with the extant right of way and demand is the Sac-SF line, but the state will not let them do it because they want the Bullet Train to Nowhere instead.
I could see some possibilities, but I think LA-LV is dead. Seattle-Spokane is possible, but I do not thing there is enough demand for such a service.
And the biggest problem that threads like this miss is just the area. All of Japan is around 145k square miles. That is smaller than just the state of California. And pretty much every other country listed is a fraction of the size of the US. And the others, when examined are generally totalitarian states, where private vehicle ownership is restricted, and the government regulates all transit inside the country.
When you have no choice but to use the government for travel and only with permission, giving them bullet trains is a bit like bread and circuses.
