Agree that transferring technology without retaining control is not wise. Canada transferred nuclear technology to both India and Pakistan in the 60s and 70s. Both signed agreements that the know-how was “FOR PEACEFUL PURPOSES ONLY”. Both countries now have the bomb.
On the other hand you can’t be a world leader in everything. Small countries like Sweden, Norway, Finland, Switzerland, Holland, Denmark, etc. pick their technology niche, and often with governemnt research assistance develop their unique leading edge technology.
MITI, the Japanese Ministry of Industry and Technology, selects niches where they believe Japn can compete and stay that way. In the 50s and 60s they picked precision items requiring high levels of skill (cameras, optics) and electronics since these needed few raw materials, something Japan does not have. Cars came as a result of the Korean war, where the US pushed the small Japanese car industry in making vehicles. They learned an immense amount; early Toyota Jeep engines were carbon copies of the Chevy 6, but smaller.
This method is called Industrial Strategy, and most developed countries have one. Britain’s strategy is basically (with some exceptions) to de-industrialize, and keep doing research for sale to others, since neither their detail engineering or their manufacturing is cost-effective. Ricardo Engineering (and Lotus Engineering) is a good example of a leading edge firm that does not build the engines it helps design for others.
The problem the US has it its federal nature with all states wanting to do their pet things, not necessarily in the national interest. As well as influence peddling, favoratism, etc. By contrast, the French president is not married to the nuclear power industry; it’s a collective decision that this industry is good for all of France.
A very strong federal government such as in Germany or Sweden will decide what type of technlogy has a future for the country as a whole and procede to help it develop accordingly.
Sophisticated public transit is good for America, but it needs government stimulation to develop it further. Aside from Arnold Schwartzenegger, I don’t know who would support it.
