It should surprise nobody that an authoritarian, centrally planned, and massively resource-rich country can perform infrastructure miracles. You don't have to stoop to conspiracy theories to understand this.
Some of the infrastructure has lead to extra economic benefit beyond just the infrastructure stimulus. But other infrastructure might not - and i would call them economic waste (but not political waste).
The building of those rail networks is meant to achieve a political purpose, rather than an actual productivity increase. Perhaps their leadership thought it was worth the spend, but this sort of spending would unlikely work in the US imho.
With freight, if you consider all factors, road is much more efficient for all but bulk loads or edge cases.
You can make more economical runs per month with trucks than with trains, meaning you get to have less stock on hand as a buffer on both ends.
This has many knock-on efficiencies - fewer resources tied up in goods, lower insurance expense, lower warehousing cost, and above all: a more flexible and responsive supply chain.
China expanded high speed rail that can't be used for freight. It makes perfect sense to connect megalopolises with such a network. But when you start building out to Podunk provincial towns when the passengers can't afford the high prices, they'll continue to take the bus. Meanwhile your shining example for modernity and progress turns into a debt bomb.
The maglev in Shanghai isn’t very usable: it doesn’t go to the city center, just somewhere remote in pudong. It is fast, but if you need to get to the airport from somewhere except one or two places in Shanghai a taxi would do better. But definitely ride it once.

You might want to read a bit about the Space Launch System, a well-known political jobs program that many consider a hindrance in advancing the art of space flight.
