American consumers are addicted to Chinese goods. Americans would revolt if they had to stop buying cheap trinkets. The Brits and Americans got the Chinese addicted on opium 100 years ago. Now it’s pay-back time. What goes around comes around.
If they can spy, all the more power to them. It’s all part of the game. A lot of American technology was previously “stolen” from Germany anyway.
But yeah, we should worry about retaining Chinese academics in America rather than spying.
