What worries me is this. When the USA began, it had the advantages of unrivalled geographical and natural resources. It had a growing population with a diverse gene pool to make use of them. Then a manufacturing economy developed to support all this. And then various service industries evolved to support the manufacturing economy and its industrial base, and then a world class R & D and academia was able to emerge, supported by everything else. And now the manufacturing economy is being dismantled, and people in high places say "well, we don't need that, we've got aerospace and world class universities etc etc, we'll do the advanced engineering here, and all the nuts and bolts manufacturing will be done off shore". But we all know what that will lead to eventually. If you pull out a link in the chain, everything collapses. When you design a piece of machinery even now, at an early stage of the inevitable decline to come, you usually cannot build it without Japanese and German components - and when its finished, 95% of the technology of the machine is in those components. America's industrial base is disappearing, little by little, year by year. Even a lot of aerospace manufacturing is done in Japan, Taiwan etc - its surprising how much - the general public would be amazed if they realized and it was written and talked about. All you hear about when this sort of thing is mentioned on a political level is the loss of jobs - which is undoubtedly serious - but the deepest problem is the loss of industrial base. I once read that Ludwig Prandtl had many of his scientific "Eureka" moments while walking around machine shops - not laboratories. I also think there should be more engineers in government. I remember hearing somewhere that 80% of the people in government in Singapore were engineers. Of course, someone is going to say that this isn't Singapore, but it will be before long if we don't watch it.
