You are in a minority when it comes to that. Most people still go to Amazon (me included) because it is far easier to find what you want there for a lower or at least more fair price. Convenience is what dictates this kind of stuff, and Amazon, work practices apart, is know to deliver stuff really fast and cheaper than most, being the most convenient choice the same way Google is the most convenient choice when it comes to web searches.
So because people are too lazy to go to a different website we must destroy the company of a very skilled businessman who's services millions of people use and enjoy?
Amazon is #1 because they are the best, not because they are evil. Google is #1 because they are also the best, not because they are evil.
That's what they have been focusing on for the last few years. A lot of the money they have reinvested has gone towards physical infrastructure (data centers, fulfillment centers, courier vehicles). Not only are they gaining a monopoly in moving physical goods from A to B but also information through AWS. You may not use their services but an increasing number of people are using them regularly.
