> It has been almost 20 years since Amazon got started. When are those mythical monopoly price increases coming?

They're already here! Over the last few years Amazon has become notorious for the level of counterfeit goods making their way through their storefront - including Prime[1]. With moves like mixing supposedly identical goods from different sellers in their distribution centres, Amazon seems to be indicating that they don't really care about this problem - regardless of how much lip service they pay it. In effect, they're getting some percentage of their customers to accept inferior goods for similar prices. I don't think they could get away with it if they had robust competition in online retail.
