Who said anything about a centralized government system?

We aren’t comparing capitalism to that.

We are comparing a deeply broken antitrust regulatory environment that is ending capitalism, or ant least the free market competitive style of capitalism you are romanticizing, and replacing it with leveragism or legal cartels or whatever you want to call it.

Amazon is a failure of underregulated capitalism because it’s not possible for anyone to compete with them.

Amazon should have been required to split off AWS from Amazon years ago, and I’d say there’s a very good argument to be made that their fulfillment business constitutes a national monopoly. FedEx and UPS don’t actually provide the services that FBA does, which makes Amazon a monopoly.
