If, on the off chance, two years into the financial meltdown you still don't quite understand how everything played out, then I highly recommend reading this book.
It's chick lit, but it's chick lit done well. It's also a wonderfully voyeuristic (and realistic) portrayal of life on the moneyed Upper East Side, right down tot he competitive preschooling and slightly absentee fathers.
Best part: It's written by Alexandra Lebenthal, of Lebenthal & Company. I tore through it in three days, often keeping TR up since I had the lights on.
