US courts and regulators recently rubber stamped the T-Mobile Sprint merger, ignoring forty years of history showing how US telecom megamergers almost always result in less competition, higher prices, and fewer jobs. Eliminating one of just four US wireless carriers is likely to result in higher prices (see: Canada or Ireland). Wall Street analysts and unions alike predict the deal could eliminate anywhere between 10,000 and 30,000 jobs, and data suggests the consolidation could result in employees across the sector making less money even if they work at other companies.

Like most mergers, T-Mobile and Sprint executives have spent a year telling people none of this will actually happen and critics were being hyperbolic. Executives like John Legere insisted repeatedly that the competition-eroding deal would somehow increase competition and create thousands of new, high paying jobs. Early returns on those promises aren't looking so hot.
