You don't need a totalitarian regime to get modern infrastructure. That's just a ridiculous statement.
Eg. looking just now London to Manchester takes 2hr and costs £88 single. I think most brits think I'm not paying £90 for a single I'll drive (3 or 4 hrs), rather than I need it to be 30 min quicker - lets drop $100bn on a new line.
I've tried to dig for references, but it's very difficult to find discussions 2+ years back, let along official news.
The USA's rail system is shit because of lack of investment, and misaligned incentives. It's cheaper to fly, or drive, than to invest in rail, even though rail is very efficient (and i suspect, more environmentally friendly than either of the above).
Note that average real-world occupancy rates of vehicles is 1.5, so that is not to say that rail is more efficient than automobiles. But merely 33% more efficient per passenger-mile than automobiles at the current fleet mpg of 25mpg, which to me was very surprising.
At 60mpg and above (EVs in particular) the automobile at existing occupancy rates is more efficient than rail per passenger-mile.
Part of the challenge with rail efficiency is that it's a fixed point-to-point transit and not a dynamic door-to-door transit. So getting from Point A to Point B has significant wasted overhead distance traveled.

Unfortunately you don’t really get one without tending to get the other.
