This may have something to do with motivation, and with the resources committed accordingly. Netflix is a TV and movie company, and it saw original content as a life-or-death strategic imperative. So it gladly spent $100M on "House of Cards," right off the bat. Amazon is a much larger, more diversified retailer, for whom TV and movies are but one small slice of a much bigger pie. Amazon hasn't taken this area as seriously as Netflix has, possibly because it doesn't consider the mission to be as central to its very existence. Its output, to date, has been fairly unimpressive and unambitious. ("Alpha House" and "Betas" have high-caliber casts and writing staffs, but word on the street is that the shows were ordered and rushed into production as a competitive answer to Netflix's recent successes.)
If, on the other hand, they use their monopoly position to illegally crush everyone else, then raise prices until the next time they have to crush someone, you have an antitrust case. And note that there's already more than a whiff of accusations about the former going on, that they are using Amazon stock price to power a market domination move which they will then use to monopolize and extract rent. It's a bit hypothetical at the moment, but it's not as if nobody's looking for this to occur.
Amazon's stock price is, IMHO, pretty clearly predicated on the "crush all opposition than extract rent" model being what the market expects to see, incidentally. Stay tuned.

Maybe you can... wait a little longer?
