It seems kgun's questions are more toward a developing way of doing business rather than a problem caused by greed.
So far, all I can see is a change from the necessity of a brick-and-mortar retail store to electronic shopping. We are exchanging our time and gas for UPS shipping charges.
The same goes for virtual products that can be downloaded or information that can be transmitted. Really, what is changing other than the mode of purchasing?

As for manufacturing and sales of real goods, are we not already in a global exchange? NAFTA was not the result of the Internet. Even WalMart tried to sell only American-made products but had to quickly convert. Our gripe about the demise of a non-virtual marketplace has more to do with what we want our salaries to be at. Five bucks an hour doesn't get it any more for us, and that has forced manufacturing of real goods overseas. We voted for that with our purchasing preferences.
I sell caps and visors. We offer American-made hats, but nobody wants to buy them because of the price.

While it is an established economic principle that the service business does not create economic wealth because you are not creating anything, nevertheless, that is balanced by the extending of our economic borders to a global economy, which in turn, balances the equation. Now it is not a matter of national economics, but one of global proportions and interdependance.

No, I don't like it either, but that's the way it is going. And digital ecommerce is making it possible by eliminating the old warehouse/distribution methods and the reliance on physical location.
