True, heavily regulated government sectors struggle from this(medical for instance), but online is nearly anarchy. I don't see Amazon having ability to screw customers (forever).

And those sectors you are talking about need serious reform that the incumbents DONT want.

Regulated sectors are indicators of markets that aren't competitive since regulation tends to come in after it's well past obvious that markets have failed. When Amazon gets to their end game (which they seem to be pretty close to IMO) I think you'll be surprised at how much and long they'll be able to screw customers... after all, most of their competitors will be long gone and the few that remain will be weak so who's going to be able to offer an alternative in the short to intermediate term?
