So, a competitor could also invest a lot, drive out competition, be the most convenient, build themselves an extremely strong position then reap the rewards ? This strategy can be replicated, thus is subject to market forces
The market today is extremely different to what the market looked like at the time Amazon worked their strategy, it was dominated mainly by physical retailers that may have required a long drive, things were not always stocked, limited choice on what's stocked on shelves. And ordering over a phone from paper catalogs had long delivery times and limited information beyond just a picture and short description. Amazon disrupted the industry by changing all of this and becoming the first major online retailer.
You won't be able to just replicate their strategy, and they've spent ridiculous amounts of money on next-day/same-day delivery infrastructure that nobody's gonna be able to invest that much. But if you do have any ideas on how to disrupt Amazon and be more convenient than them in 2025 let me know :)
Plenty of people do want to make the efforts and have tried. Physical retailers like Walmart have opened online retail but adoption remains limited. Startups like Jet.com, Quidsi, Fab.com, Rakuten/Buy.com, Woot and many others have tried and failed to take on Amazon, leading to bankruptcy or being sold. The reality is that nobody can take on Amazon due to their slimy tactics but also nobody can realistically provide something to customers that Amazon doesn't already provide. Fees will keep increasing and costs inflating as much as Amazon wants, while customers are none the wiser and sellers can do nothing about it.
What you say is contradictory.
If fees and prices are increasing on Amazon it means more potential for the competition if they can operate with lower margins.
Amazon is winning because they toe the line, not because of an innate monopoly.
If you read the parent comments we've already established that Amazon punishes sellers for pricing lower on other platforms than Amazon, and Amazon's margins affect item pricing everywhere. You could have zero margins, you could have negative margins, Amazon will see that Seller X's items are available on your Amazon competitor for $2 while it's $20 on Amazon and say that they're in violation of policy. Unless you make it worthwhile for Seller X to abandon Amazon you will not be able to compete.
You can't realistically compete with a Monopoly like Amazon. They'll buy you out way before you can be an inconvenience to them, or drown you by artificially lowering their price until you go bankrupt if you refuse their deal. And even in the off-chance you somehow replace them, then great. We're back to square one.
Sure, "a competitor" with hundreds of billions of dollars and a few decades to burn could, in theory, do that.
But what would be the payoff? Getting to compete head-to-head with Amazon? Amazon, that's a well-established incumbent, with a well-known pattern of ruthless dealings, including leveraging their ties with governments, to protect their monopoly?
No one's going to be able to make a profit doing that.
"The market" is not a real entity with desires and opinions.
"The wisdom of the market" only works with an ideal free market, or something close to it.
Such a thing has a number of requirements, such as low/no barriers to entry, perfect information, elasticity of demand, etc.
Those do not exist here. No useful information on how things "should be" can be obtained from the fact that Amazon cannot meaningfully be challenged.
Your position, essentially, boils down to "however things are right now, if they're even remotely stable, that's how things should be, because that's what the market wants." Worship of the status quo.
I’m only criticising Varoufakis point of view and some people arguments here. Of course I have some things to say about Amazon… and yes information is never perfect
