American Credit Crunch

Surely the recent goings on on Wall St have a massive influence over our lives?
My understandiung of the situation is this-
The American Poor were encouraged into home-ownership at a time of low (1%) interest rates, given easy credit, which enabled them to mortgage themselves to the hilt at 1% interest.
When interest rates couldn't be sustained at the low rate, & invariably went up, the American Poor were the ones who hit the wall first- being in behind the 8-ball to start with, & then getting worse.
The catch here is this- in America, if you can't meet your Mortgage requirements, you simply deliver the keys back to the bank & walk away from the mess. What an absurd situation!
Hence, all of a sudden, banks who've borrowed money to on-sell lose their income stream (mortgage repayments), & are left holding the bag- literally .
This chain of events has sent a few of them crashing, hence the the recent spate of events, & their effect on Wall St & consumer confidence.
Australia is more regulated than the US when it comes to this, so this scenario is unlikley to happen here, yet their market instability affects us all- especially those who are close to retirement/involved in short-term trading.
Is anyone here affected by these recent events?
