What actually happened, and continues to happen, is that Europe and the EU became entirely dependent on US tech and other foreign industry. It wasn't just a matter of "see what works and then copy it domestically". It oursourced basically everything.
To be fair, it was mostly outsourced to China, at least in Slovenia with our electronics development and manufacturing (Iskra and Gorenje). US stuff has also always been more expensive in every category except software.
