It would appear AWS is the entire profit Center of Amazon.

With Amazon retail business being run as a non profit, until such time as conditions compel Amazon to raise prices higher.

If Amazon’s shareholders allow Amazon to continue running retail as a non profit(as they have for over 20 years), then I think this will continue until Amazon maxes out at whatever the ceiling retail market share is for a single company.

But I think Amazon’s non profit retail land grab could continue for another 10-20 years.

Besides shareholders stopping Amazon, I envisage the only things that can stop the Amazon Borg Cubes are:

1)Government regulatory “shields” being raised

2)Web/Cloud Services getting ruthlessly competitive and margins plummeting.

Just my personal thoughts.
