I would certainly disagree with Smith in that there isn't actually anything special about manufacturing in that it alone can create economic growth and prosperity. New technologies and disruptive innovation have the potential to reverse the trend, I think. That's what happened with the internet.
The more an economy develops, the less manufacturing component there is. In the US, it is barely a third nowadays.
Which means what? After all, manufacturing has always generated some pretty well-paying jobs. My parents' job manufacturing sunglasses in Central Massachusetts helped put me and my sister through university.
What happened to those jobs, back in the 1970s is indicative of a long-term trend that started then. They moved south, then to Mexico and finally to China. Frankly, some of those jobs putting sunglasses together could come back to Central Mass. if they were highly automated. I don't see that happening, but it could.
The other side of the sad jobs-coin is that Services Industries, which generate the other 70% of employment, do not provide all that well-paying jobs. Just walk into any Wal-Mart or Macdonalds to witness that sad fact.
What's a country to do? If I had a magic formula answering that question, I'd patent it.
But a formula exists nonetheless, and it is an emphasis on Tertiary Education that will provide the sorts of sufficiently-well-paid jobs at decent salaries. Which is why we see the tidal-wave of students studying at MBA-classes. Frankly, I teach classes in International Business, having had just that as a career. I find MBA-programs supercilious in nature. You do not need an MBA to go out and sell a super-computer.
Whatever your product/service, you need a talent for matching a customer's needs with that product/service, to convince the customer of the necessity to buy your proposition. And nobody is going to teach you that observational skill if you don't have it innately.
Fortunately, there are a good number of other Services Industries (See the list
here). My point being that there will be plenty of choice for those who are sufficiently ambitious.
But a blind belief that technology will be there to provide the jobs a nation will need to assure full employment has been shown to be a false prophet. The Information Technology industry started just post-WW2 in the US and has come full circle. IBM's revenues no longer come from computer sales as much as providing Computing Services. Computer manufacturing companies are a diminishing breed. The cloud is everywhere and systems-interconnect with ultra-large systems that do the number-crunching is easy to do.
So, what is the NBT (Next Big Thing)? I dunno. I keep looking, but I see nothing with real "legs" generating jobs far into this New Millenium.
Maybe Electric Cars for the masses, but that's not sexy - just long overdue.
So, sorry to say, but I cannot share your enthusiasm for New Technologies, which will create substantially well-paying jobs for all and sundry. Some yes, but certianly not all ...
PS: Frankly, I suggest we need slower population growth, and better jobs/lives for the lower population of Americans.
