A hundred years ago many Americans (mostly old ones) said the same thing about America's soaring manufacturing sector. They'd say that factory output's not important because we don't need it. Only thing we really need is to eat and that's what farm output's for.
Reality is that a hundred years of U.S. manufacturing changed to the world, and now we're seeing just ten years of U.S. innovation changing it even more. My personal guess is that those that don't see it are those that really don't want to see it.
I hope you're not planning a visit to Vegas any time in the future.
