> why is "investment" the primary benchmark? I agree that dollar amount is probably not the best metric, but it was one of the metrics that companies argued would be reduced as a result of common-carrier regulation. So, I suspect this article is a direct response to that. Despite the likely existence of better metrics, since the companies claimed investment would be hurt, it's useful to actually examine their claim directly.
