Do you even know what "AAA item" you are talking about? Of course not. Your post screams it.
All those AAA "items" were products created by the financial institutions out of the underlying assets, not bought by them. They were SOLD by them.
Who did they sell the MBS securities that were AAA rated to again? Thats right other banks, financial instutions, and other investment firms such as those that handle many americans 401k accounts.
Don't be a hack dude.
Wrong. They sold CDOs and other higher order products to 401k fund managers.
In order to build a CDO, you need an underlying asset. And if the demand for CDO products is great, which it most definitely was, then that means you need an astronomical number of underlying assets.
Which means you need your brokers to hit the pavement and start signing people up for home loans, HELOCs, auto loans, credit cards, whatever it takes.
You then take these assets from your supply chain and package them into CDOs. You then sell the pieces of these CDOs to 401k fund managers, state pension fund managers, city treasurers, Saudi princes, Rockefellers, trust fund babies, and so forth.
These clients thought these products were the greatest thing since sliced bread and wanted more, more, more.
Take a look at the fine print of your 401k. When a fund says it buys a certain percentage of government "bonds", you probably think those are municipal bonds and Treasuries and whatnot. And some of them actually are. But if you read the fine print, you will find the word "bonds" also means "bond derivatives". And THAT is where the shit hits the fan. THAT is where people like you are completely unaware of what is actually going on. You stopped a mile back and got hung up on "loans", thinking that is the source of the problem.
Quite the opposite. Toxic loans are the SYMPTOM. They got greedy. They figured why give a guy a $100,000 loan when we can talk him into a $200,000 loan and make more profit off the interest payments from him?
And when he balks at the high monthly interest, we show him how he can use a sub-prime loan to lower his monthly payments and then when it resets, we tell him he can just refinance.
Don't believe me? Stand by. Evidence bomb is on its way.
