If the status quo when Amazon started was a high minimum wage with strong unions and employee (or at least local) ownership, this might be a more compelling argument. As it is, the capitalists in Bentonville are losing out to the capitalists in Seattle because the former rely on massively state-subsidized labor while the latter just axes the labor all-together.
I'm not saying it isn't a problem, but this isn't something that was created by (or even made worse by) Amazon. This is an important point because without a proper diagnosis, we'll never find the cure.
Also, Amazon beating Walmart is an exemplar of free markets at work -- one competitor besting another on merit alone (actually, even DESPITE massive federal and state tax incentives propping up the losing side!) Maybe the conclusion you should be drawing from your dislike of the status quo is that free markets aren't a panacea after all?
Finally, I'll note that Amazon distribution facilities -- for all the valid criticisms -- at least pay a (barely) living wage in many areas. Walmart pays substantially less.
Let's not get carried away here. In the most recent quarter, Walmart had revenues of $123B vs Amazon's $38B. Walmart still has time to figure out the ecommerce game.
The former may be true; not sure about the latter. Existing anti-trust law could be sufficient to deal with them, if the powers that be had the will to use it.
You're proposing that the solution to "the Walmart problem" is to create a company even worse than Walmart, a company that drives other, larger companies out of business? Whereas Walmart put out the mom and pops, Amazon is putting out the Bestbuys and shopping malls. There is no difference. But people are celebrating this, and heralding a coming age where no one has to work (caused by Amazon-like processes and robots replacing retail workers and other jobs), without really considering the complete disaster that this would entail. The solution is not even more supercompanies.
Free markets are a travesty of economics; bring back competitive markets.
