Lol are you high? Amazon isn’t even the cheapest option in many cases and hasn’t been for a long time. They’re a terrible company that literally extorts merchants, authors, and businesses. Just look at the cut Amazon takes from books, for example: 65%!

You’ll see in that editorial just how much Amazon fucks over authors (many major authors have begun refusing to sell books and audiobooks on their platform). And that’s just a tiny fraction of all the fuckery Amazon is involved in.

You’re also being completely short sighted if you believe Amazon isn’t going to begin price gouging the shit out of everything once their market dominance is utterly complete. Monopolies are illegal for a reason. Just read up on the Robber Baron Era of the US to see how bad it gets when monopolies go completely unchecked. Sadly, we’re pretty much reliving it already, as Amazon isn’t the only company doing this type of bullshit, which you rightly pointed out in regards to other rackets.
