Since the 1990s...
...I have direct experience of teams of Chinese and Korean specialists being invited to GB to see our shiny and innovative systems and procedures. The PHB thought he'd won the lottery, believing they'd buy all "his" stuff.
The rest of us noticed how the visitors were asking the workers a myriad of questions and taking copious notes. We knew immediately that there'd be no sale, just copying and development of similar processes and systems.
Multiply my experience countless thousands of times, and we end up with today's situation. It's nothing to do with nationality or race, it's just human nature, including our PHBs being naive and greedy beggars.
