Business 2.0:

"Money comes from consumers. If you sell screws to Seagate Technology, which sells hard disks to Dell Computer, which sells Web servers to Amazon.com, everybody in that chain is getting paid because Amazon sells books to consumers. Everything in B-to-B markets–steel, software, whatever–is being sold somewhere down the line to a company that sells to consumers."

If only more people made sense as Clay Shirky does.
