To wax metaphorical, I'd rather the monsters devour each other while we race for a super-weapon to defeat all monsters and protect real people.
This situation where corporations are effectively replacing the state is not exactly what I had in mind when I said the world would be a better place with a diminished role of the State in individual life.
I like the term empath75 uses to describe this situation - 'corporate feudalism', because it really does feel like lords battling for power and influence, while an increasingly impotent state looks on doing little more than wagging its finger.
Counterpoint: I like shopping at Amazon. I used to work there too, but I liked it prior to working there, and continued to like it after I quit.
And I think it would be very difficult for a company to offer the level of convenience and good UX that Amazon does at a much smaller scale. For example, part of why they can get very fast shipping down to a reasonable price is their huge network of distribution centers + their size giving them leverage in negotiations with UPS/Fedex/et al.
If you split Amazon into a dozen smaller companies, the overall customer experience would likely be worse.
The only way you can prevent feudalism is by preventing accretion of power. Otherwise, it's a positive feedback loop through and through - the rich get richer, the powerful get more powerful. How exactly to do that is up for debate, and I see socialist democracy plus regulated capitalism as the most practical current answer. Unfortunately it's not a stable position and is prone to failing if any one side can't be kept in check by the others.
Hasn't the same thing been said about Walmart?
