“Throw more money at it.” That’s an old suggestion for trying to solve problems big and small, but it’s a solution that rarely works, because it doesn’t address the root cause of the problem in question.

Recently, FCC chairman Julius Genachowski outlined a plan to promote growth in the mobile communications sector, including a proposal to give mobile operators more spectrum. That’s bad.
