Scaling up requires millions of euros typically, to install new machines and educate new workers. Typically you need investors for that. If there are no investors, it's hard to make it happen.
This is not the same in China where the state can just give an order to build more lamp factories. The state needs hard currency for high tech stuff and materials that are valuable on the international market, but all of the workers are paid in the internal coin of the country which is worth a lot less on the international market afaik, if their economical system is anything close to that of East Germany. I know a bunch about the DDR but not specifically about China.
This is certainly a kind of single-sided snobbish leftist point of view thinking of China like a cheap slave labor camp. While Chinese are known for copycat designs of course, and government sure invests in technological areas (which is not a bad thing) China is moving away from blindly copying to creating original products. Look at modern Chinese microcontrollers like Rockchip and Allwinner. Or last scopes like Siglent, Rigol or Micsig. These blown all low-mid range Western scopes out of water for good. And these manufacturers are going to aim in high-end sector too. And Chinese salaries are actually on the rise, not to be considered third world any more. On the lamp topic, I have two Philips HPI-T lamps, Belgian and later Chinese. Chinese one is certainly better made.
And are you kidding saying CNY "is worth less" ??
