Telecom is a horse of a slightly different color though because they are intentionally granted regional monopolies over utilities. There should be better regulatory enforcement of these utility deals, but between regulatory capture and nearly trust-like brokered deals to swap regions among each other to best minimize any particular region's regulatory control and collusion opportunities between neighboring regions, almost all of the regulatory enforcement that should prevent certain types of monopolist behaviors has nearly no teeth left in the US.
