Ehh this article is poorly argued, there's way better writing on China's economic performance.
The author starts by just ranting about things they dislike (DEI initiatives, preventing the spread of a pandemic) rather than building a case for these factors being causal. It's also got some casual/unaddressed anti-communism in it.
yeah, read against the grain there are some useful insights and it's certainly a weathervane for how the more business savvy people in the west are beginning to see China. Still, I don't think the author has a good understanding for what is causing a drain on productivity in the west (i.e., i don't think it's COVID measures and DEI) and so I'd take their other analyses with a heavy grain of salt too.
