Future Sounds

When reading about David Cameron's plans for Britain to invest in tourism, pharmaceuticals, and so-called green industries, my initial reaction is: Isn't that what all developed countries are investing in or say they want to be investing in? Makes one wonder, is it possible for all countries to develop the exact same industries and somehow get away with it? I mean, sounds a bit like we'd end up with the old concept of everybody cutting each other's hair.
