Can someone explain (in simpleton terms) what mortgage-backed securities are and how they factored into this whole mess? I kinda missed that part in the video.
A bunch of people with no money, whose careers consisted of checking receipts at Walmart, bought houses they had no rational business buying, via mostly no-document adjustable-rate and/or interest-only mortgages they couldn't afford to pay very long.
The banks and brokers who handed out these mortgages made up-front money via origination fees and other points. Today, they are either rich, or richER if they started out rich.
They bundled these worthless mortgages (which were never going to be repaid by the "homeowner") into securities that some not-quite-impartial-and-honest people rubber-stamped with an official seal of approval and quality rating, and sold them so that somebody else would be left holding the bag when said "homeowners" discovered that a Walmart Greeter salary wouldn't cover the mortgage when the rate adjusted or the interest-only period was over.
At some point even the *****s who bought these mortgaged-backed securities clued into how worthless they were. Most of these *****s, however, were clever enough to have the right kind of connections in government.
The federal government, in its infinite wisdom, printed a ton of money and bought up (and is buying up) much of this bad debt through Fannie Mae and Freddie Mac, two organizations dedicated to promoting the American Dream, even to people who need to wake up, quit dreaming, and rent (not buy) a humble abode more within their means.
This is a problem because, well, the federal government printed a bunch of paper money to buy paper securities worth far, far less than the paper money they printed to buy it. Ultimately, this will inflate the paper money you and I earn, save, and invest. Inflation is nothing special; just a sneaky mechanism by which governments transfer actual wealth from its productive/saving/investing citizens to fuel its own spending (which has, of late, focused on bailing out nonproductive/indebted/foolish people and corporations).
I think some people are under the illusion that the crisis passed when the housing bubble popped, but the government is still buying up bad debt and doing other dumb stuff to artificially prop up the housing market (eg, last year's homebuyer tax credit).
But I'm no economist.
