all it takes is not shopping at amazon. now, obviously, if by some awful twist of fate, amazon is the only place to buy your life-preserving medications or whatever (God forbid things ever get that dystopian in my lifetime) then my advice is silly and you should ignore it. but if someone needs some household good or even some foodstuff that only amazon has or that amazon sells cheaper than the other places, then it's time to suck it up and not get your (the general you, not you personally) favorite brand of rocky road ice-cream bars or that brand of soap that you love.
I reckon in the first world, there is nothing that amazon sells that we can't simply skip or get somewhere else that would leave anybody in danger of death or serious injury.
I know it's tre chic to wallow in helplessness wrt certain things these days but we aren't yet completely without recourse even if we aren't going to buy our way into an entirely new order any time soon.
You could also say all it takes is a competitors to actually start competing. And by that I mean offering a better product and service, not also turning them into money printing "marketplaces" selling chinese crapware which is what they are doing instead, except without the remaining customer service guarantees that Amazon hasn't yet gotten rid off.
Or all it takes is regulatory agencies to wake up. After all, preventing the tragedy of the commons is their entire reason for existence. In fact, it's the only reason we give away a large chunk of our income in taxes.
It’s not that we don’t have an inability to deal with small inconveniences; we haven’t the time and resources to compete with those who are faster because they tolerate monopolies and anticompetitive actors.
