Western hardware startups on X/Twitter have been posting about how they are doing CNC + anodizing + transport of parts from China for prices that are close to the material costs of the part. The only reason this is possible is because the Chinese state is subsidizing every value adding step of manufacturing.
What I don't understand is what does the Chinese state get out of subsidizing my orders on cheap-chinese-cnc.cn and cheap-chinese-pcb.cn and why are other countries not doing it?
Subsidies are actually good for the economy. If you invest a few billions into electronics, that allows higher salaries for electronics engineers. The higher salaries mean that people will do electronics in university, and it pays back in a few years.
I feel like some countries avoid them for cultural reasons. Partly because it could be seen as a form of corruption - chicken farm XYZ pays $100m to support both parties during the election, and suddenly there are $10B in subsidies for chicken farms after the election regardless of who wins. Most countries have more than two parties, so this can also get expensive. China has only one.
Some places have the bubble problem - electronics salaries are too high, and further subsidization increases the salaries past sustainable values, which may also increase the cost and price of the products.
Some subsidies are more subtle, e.g. a lot of US tech is indirectly subsidized via military contracts, which also does the work of filtering corruption.
