I actually researched the patriot act extensively for my dissertation for my masters degree. I did not research so much the credit card end of it, but I can say that despite it's bad reputation, it did do a lot of good with US government agencies and cleaning up and streamlining their processes.
I did also find that while it's been touted as the worst thing for personal freedom, in reality, personal freedom has been eroded since after WWII, slowly but surely each president has added on their own ways of acquiring information for protection purposes. Bush only did it very openly and without any thought or remorse for the reaction of the american public.
And a funny thing about credit cards - I did the same thing leaving college. I bought somethign at Old navy with a store card, moved out of my dorm and forwarded the mail. Well, that one piece of mail never got forwarded. I caught the company just before it was given up for collections. I paid it and it still mars my credit report. I just checked it again and found they messed up a lot of information b/c i have been using my parents' american address for a lot of information. They said my dad was my spouse - that was scary! I got that fixed, but they thought I applied for a mortgage and I hadn't, so basically they got me mixed up with my parents. Really annoying and goes to show just how inaccurate these credit companies are.
