It seems everybody involved, in trying to circumvent so-called "regulation" basically thought that they had figured out how to bypass reality (you know, math and physics).
The country has been running on a Faith-based economic program for the last 25 years.
Problem is, many of us suckers believed them when they trotted out their Ayn Rand dreams of a Friedmanesque Utopia, where a man who worked hard and took risks would be rewarded with riches, but if he missed the mark he would need to find another vocation. If he did a poor job, or produced inferior goods, or put lead in the toothpaste, well he knew that the "market" would punish him and therefore that was the disincentive to be malevolent.
So, these guys got the de-regulation they wanted, but they ended up ALL lying themselves AND to each other. And the American people -- who couldn't get enough unearned granite countertops, and the Escalades with the spinnerz, towing the dual Jet-skis to the lake -- went right along with the boondoggle. As Rhonda states above, the risk was not only sidestepped by the primary actors, it was thought to be completely wrung out of the system. So these iBanks (NOT an Apple product, BTW) had one division pushing these mortgages on the one hand (and they were "pushing" them. I, who have never owned a home, was getting cold calls day and night from people who thought I would be interested in this or that equity loan.) and further up the chain they packaged the bonds and credit default swaps of these same crappy mortgages and sold them to the other banks and, in many cases, back to themselves.
Now these people want US -- present and future (way future) taxpayers -- to buy this crap and take it off their books. Which means, I am now a home owner, whether I like it or not.
I think Bush's comment on all of this, when he thought he was speaking off the record, is very telling: "Wall Street got drunk."
The "irresponsible borrower" meme, though, is yet another bogus "talking point" and a further diversion from what the real issue is. These "irresponsible borrowers" do not make the rules (though I do contend that not a small amount of the most egregious small-time swindlers need to serve some time in the Big House Without Granite Countertops), the
Big Boys do, and now that they've scampered off with their sushi, they've stuck US with the bill.
