You are simply deluded. You know what was NSA called before it was widely know it exists. No Such Agency. Shining a light on it will only drive the real efforts into more secrecy. Once NSA is exposed a new secret agency we won't know about will be created. I would not be surprised if the efforts were already underway.
YOU CANNOT PREVENT THIS! The state has too much power, too little to fear. You can only mitigate the worst excesses of abuse of power, which I described above. Once you force the government into accepting the above described abuses as price of getting the information it thinks it needs, there is no way back.
The Eastern Europe behind its Iron Curtain had a hope of the West breaking through and helping them overthrow the government and clean the house, but you have NO ONE. There is nobody more powerful than the US government. There is no hope for you to get any sort of external help once the repression starts. NONE. So you better not speed it up. It has already started in Guantanamo it will spread, but fighting NSA will make it spread even faster.
There is slight chance of this country collapsing economically before it can defeat Russia and China, but that would be a very small hope to look forward to. Most likely Russia will fall soon and China soon after and that will solve any economic issues US might have had, since all of the world resources will be available for the taking.
