For the last year, Sprint and T-Mobile have been pushing a large number of bogus claims justifying their $26 billion competition and job-eroding megamerger. One, that the deal will create jobs (false). Two, that the deal is necessary to deploy fifth-gen (5G) wireless (false). Three, that reducing the number of major wireless competitors from four to three will somehow create more competition (false, just ask Canadians or the Irish how that works out in practice).

There's really no debate over whether such significant consolidation is bad for the market, consumers, and employees. You need only look to 30 years of US telecom history to discover that such growth for growth's sake uniformly results in less competition, in turn resulting in higher prices, fewer jobs, and worse customer support. It's a major reason everybody hates Comcast. It's also easy to find a long, long list of companies that made all manner of pie in the sky promises pre-merger, only to fail utterly to adhere to any of them.
