I'm more and more convinced that this was always the plan. The primary effect of the Telecom Act of 1996 has been to extract hundreds of billions of dollars from investors. All of the CLECs and other competitive types of telcos that sprouted in the spring of that law's optimism have gradually been wound back into the monopoly. Ma Bell (still for the moment two "Daughters Bell") has paid pennies on the dollar for equipment, marketing, vendor agreements, customers, etc. as these erstwhile competitors have gradually succumbed to the monopoly's failure to substantially abide by (and regulators' failure to enforce!) any of the pro-competitive measures in that law.
In retrospect, it was inevitable. Therefore, it was planned from the beginning. Telco executives and bankers have personally extracted billions from all the mergers. Generations of citizens have swallowed the fiction that we ever tried telco competition in USA. Strictly regulated POTS has been replaced with totally unregulated "information services". Perennially-unprofitable operations like FairPoint and Hawaiian Telcom have been unloaded to fools like Carlyle. The inconvenient wall between local and long-distance is gone. The expensive nerds at Bell Labs got sold, so the world can look elsewhere for subsidized progress in basic technology. All in all, a pretty good deal for Ma Bell! Since it happened over the course of decades and Americans have short memories (and since the media that could remind us doesn't want to cross her), we didn't even notice it.
