That thing between your ears is quite possibly the most incredible bit of biology on the planet. Surely it's not asking too much to engage it before making one of the biggest decisions of your life?
That's not saying that the banks acted well, because they clearly didn't, and a large number of defaults is evidence of that, but it's not a good indictment of the people that borrowed too much either.
The 'boom' years were funded by people borrowing more than they could afford, and even now in the recession that caused, we still have interest rates at rock bottom levels, thus inflating away the savings of people prudent enough to live within their means, just so the folly can continue.
Shame on both of your houses.
I'll side on those who are ignorant over those who are deliberately deceptive any day of the week. Not everybody is as clever as you Bruce.
