I suggest the NSA work is a big job creation scheme, there are a lot of contractors and vendors providing services and facilities to this (big) branch of the government. A lot of tax dollars are spent on this. And the effectiveness is questionable, because it's secret. We know big federal government IT Contract outsourcing failed to deliver Health Care Gov, I suspect there are a myriad of failed systems we're just not getting to hear about. I talk about cost to the tax payer.
