So China subsidizes a lot of their factories and now they have all the factories and they also have rising standards of living so ... seems to be working for them?
The factories are not in China because they were subsidized, they are there because wages are lower. Yes, some caveats apply, there is some network effect, and you need sufficient infrastructure, suitable workforce and administrative stability to get the process rolling, but the notion that China "bribed" those industries into their country is nonsensical.
Also note that this development (low-skill manufacturing migrates to growing, lower-wage country, then the migration propagates up the tech level) is something that occured basically exactly the same way in the past (with Japan in the 1990s).
> now they have all the factories and they also have rising standards of living so ... seems to be working for them?
This is basically the point of international trade.
Things also worked out for the US, because they reaped the fruits of that cheap Chinese labor-- all-American electronics would have been significantly more expensive.
I'd also like to point out that those living standards are WAY below US levels-- there is absolutely no way that US-americans with comparable education levels would be willing to work in comparable conditions.
Note also that artificially messing with this process has consequences: If the US had forced electronics and heavy industry to stay fully domestic starting in the 80s or so (with tariffs, regulations and subsidies), then their products would have stayed much less affordable for decades, and a lot of bright STEM graduates that made software/CPU development/Hi-tech happen might have taken cushy, tax-payer funded jobs instead...
China has a demographic collapse coming so there is probably baked in inflation coming in the 2030s. The era of cheap chinese junk might go away. It doesn't just mean Aliexpress/Temu junk. It means a lot of fun things we take for granted may not make sense in a more inflationary environment so they dont get made.
If you watch manufacturing videos, its crazy how many people actually come together to make the cheap mundane things we take for granted: For example, count the number of people who touch this random RGB bluetooth speaker: https://www.youtube.com/watch?v=yFYxSX6xP2U
Maybe you could automate that, but it really would be more effort than its worth to set up robots to make what I assume is a fairly cheap product.
