It unquestionably is but it sounds like you're implying that high speed rail is some sort of utopian megaproject and not a solved problem of basic, reliable and effective infrastructure that is a great bang for your buck in every country that builds it.
I mean we actually own land in the US where it’s not owned by a person in the same sense in China. So it’s easier for the government to cease it and do whatever it wants with it
Spain has the lowest cost per kilometer in the world when it comes to building High Speed train (14.5 million €/km) and they care for the environment and don't have slave labour. Rather, they have very strong unions.
