Amazon's power as dominant seller is not OK

AMAZON.COM, the giant online retailer, has too much power, and it uses that power in ways that hurt America.

OK, I know that was kind of abrupt. But I wanted to get the central point out there right away, because discussions of Amazon tend, all too often, to get lost in side issues.

For example, critics of the company sometimes portray it as a monster about to take over the whole economy. Such claims are over the top - Amazon doesn't dominate overall online sales, let alone retailing as a whole, and probably never will. But so what? Amazon is still playing a troubling role.
