The Illuminati are the Decision makers. They had a meeting and realised they needed more funding for their Brainwashed cloning project in their outer space station, so they took the 300 Tril that suddenly went missing in the US.
Funny enough the Tax records in England went missing for 2 weeks straight with no explanation, and just as sudden as they disappeared they reappeared, and the staff was just stupified.
Nasty little Illuminati. We wants it for our seeelvvvesss..
As for who to blame? The fools who bought without a second thought. The fools who were Flipping, raising the prices to such a level that when it fell it fell hard, and the fools who thought, "Oh hey! The Re-sale value is much higher! Let's put the OP at a much higher Value!"
Though I think it's just the fact that banks stopped lending.
