This high-speed rail project is a warning for the US

Vox basically did exactly this: [VIDEO] tl;dr: US regulation makes it too easy for individuals to sue and stall megaprojects like this into nonstop litigation

Why even mention wars? We have the money for Hyperloops, Solar Freaking Roadways, Boring Company, and so much more... you know... terrible ideas that clearly won't work, don't even pass a sniff test, but we throw millions or sometimes billions at. I'm totally okay with pushing the bounds of what we can do as humans, and even encourage it. But running on hype is not a sustainable system and arguably fraudulent (I believe it is). The Bloomberg article sure makes Hyperloop look like it is... I different version of hype applies in a different way. With the systems destroying themselves through compounding "compromises" to get political allies. It's a Vox video, so high level but not a bad intro[0]. Tldr: easy to derail (pun intended) any political project, and the bigger the project the easier it is to derail. [0] [VIDEO]

you're right that labor is only a part of it. but part of the reason why the CA project saw huge rises in costs is because of project planning and scope increases in the planning -- both of which are politically driven. part of the politically driven issues stem from NIMBY-ism but the other (arguably more heinous) part is how the cities can force the plan to be re-routed [1]. not only do costs rise and opening dates delay, the hypothetical "high speed" nature no longer rings true.
