Only in very simplistic theory. :(
In practical terms, businesses with high margins seem able to afford government protection (aka "buy some politicians").
So they lock out competition, and with their market captured, price gouging (or close to it) is the order of the day.
No real sure why anyone thinks the playbook would be any different just because "AI" is used on the production side. It's still the same people making the calls, just with extra tools available to them.
Weird that the field of economics just keeps on existing.
