These laws work a very specific way and have very specific controls in place to prevent shit like you describe from happening which you could go and read up on if you wanted to but it’s much easier to fear monger amongst one another because it plays to your ego that somebody who is important enough to be under surveillance by an intelligence agency.
And of course this applies not only to the NSA spooks, but all the way up. You shouldn't be any more comfortable letting 'the government' spy on you, than you would be letting me spy on you. If you want another example along the same lines, spooks spying on their love interests is so common that there's a slang term for it - LOVEINT [2]. Basically, don't grant people power over other people unless it's really just completely and absolutely necessary, because it will be abused. So the benefit needs to substantially outweigh the inevitable abuses. And in this case, that obviously doesn't hold.

One does not have to be “important enough” if they are conducting mass surveillance and storing it in a database indefinitely.
For what is worth, I'm quite left leaning and fully agree with the parent poster. Information is power, no matter which party or in which country.
