Re: Excellent article - b u t -
I agree that there is a place for us as a service-providing nation, but I don't believe that we can unilaterally raise the standard of living over the next 50 years worldwide without sucking a hit down ourselves (Not that I mind not having a new TV every year so that someone the other side of the planet can have a job that pays for plumbing, I should add). More to the point, I don't see how we can do it ethically. If we can only be a service provider unethically, then frankly we deserve to take that hit to our standard of living.
As a species that we have created certain corners of the market that we'd be better off without, created the desire for certain products and attempted to educate via media in developing nations that 'our' services and culture is better than local services and culture. Looking at your list:
Pharmaceuticals - The questionable morality of massive corporation making money out of people in backwards countries suffering from disease. This could be a 'clean' service industry, but a quick look at the habits of GSK shows that it is far from being such. Why cure things when you can make more from treatment?
Architecture, higher education - ultimately things which can be done in-country once we've built up a decent education system there.
Aerospace - The idea that 'you're not a country unless you have an airline' has dropped aside to a degree, which predominantly leaves the big money in military aviation. Like the Al Yamamah deal with the KSA.
Pop-culture - The question of if it is ethical to bombard developing nations with our own culture, performers, morality and values in an attempt to make money and imprint those values is very dubious. Ours is a culture based heavily on sex and drinking. Who are we to brainwash a generation in a developing nation with the values of rap-stars?
Building services - I've already said my peace on the ethics of (re-)building a nation's infrastructure and living off the interest for thirty years.
Finance - Growth areas for the UK: Moving numbers around and making them larger without adding any real value.
Access to legal services - Developing nations have lawyers and mostly get on fine. Are we talking about exporting a bunch of lawyers to litigate on such matters of auto accidents and patents?
In short, a lot of the things and services we are making a buck off are morally dubious. Actually, it's morally dubious to sell them to fellow Westerners - it's downright appalling to turn a profit out of some of them from people in the Third World.
In real terms perhaps you are right: Perhaps we can continue to inflate ourselves as 'service providers' and sustain our standard of living at current levels. I seriously doubt that we as a society will be willing to lose that second car just to do it ethically.
