Yeah, its nice. Authoritarian regimes usually have some nice prestige projects to show, which is really nice if you are a foreigner they are trying to impress, or a local that is in favor with the regime. Not so much if you are out-of-favor, whether because you opposed the particular approach they took for the prestige project or for some unrelated reason.
But, as much as I like HSR and wish the US would do it, emulating China -- whose ability to do it isn't a mystery needing study, but well-understood -- isn't a cost worth paying for it.

I'm not exactly pro-prison, but so far I haven't heard any alternatives that I believe would work as a solution to violent crime. I'm open to suggestions. It is certainly the case that the U.S. has too many laws.
Here is the Chinese high speed rail built in the last decade, it is not propaganda, it's literally something you can buy a ticket for and travel on at 350 km/h right now. I truly worry for Americans incapable of seeing what is happening in the rest of the world.
