Thank you to EE-BO and everyone who responded about this, I'm still pretty confused, no matter how many times my dad tries to explain it to me, I understand the basics about the ARMS and credit crunch but it's so comprehensive, it's overwhelming I guess, also because I have so many other things that I'm worried about....
Idk if any of you are interested in this, but my dad works for Bloomberg and wrote a series of articles about most of this stuff, just thought i'd pass it along. Plus, i'm pretty proud of him, even if I barely understand what it is all about.
