There are a handful of people stealing technologies though and the point I want to make it ITS STATE SPONSERED. China gives you a handbook on how exactly to steal technology and how to bring it back. The STATE SPONSERED stealing of tech in specific fields is the problem and is estimated to lose the US $150B every year according to a bipartisan report not including the rest of the world. The CIA estimates thousands of government trained espionage operatives are present in California alone, far more than any other country has had ever and this doesn’t include the Confucious Initiatives all over the country. This isn’t a Chinese problem at all, it’s the government of China specifically CCPs fault that should be countered by government policy not mistrust.
