Sortedmush, thanks for the links dude!

To Sjalq: Now I pointed out to you a place where you can see the things you asked me you change the question. Now you want my interpretation of the situation.

1. Crack of 29 showed you just cannot mix finance with real economy. Laws were implemented for normal banks not to go the financial speculation route, in order to protect citizens from another crisis. Surely they were not perfect still, but better than nothing.
2. Then came the time 29 was forgotten and finance prophets managed to throw down all those laws. One at a time of course, so we wouldn't notice where we were headed. Since 80's to 10's. Banks started to invest in finance and invent "new and exciting ways" to make money out of doing nothing.
3. Not only that, but some smartass thought that if you gave loans to people who couldn't pay them, combine them with other loans, have rating agencies rate them AAA++itsawesome and put them in the market HE would make a fortune. So they did. That was the spark. Where that lead us is widely known.

In the docu they compare that with an oil ship. Those ships have to have compartments tightly sealed, or the oil would just bounce back and forth and sink the ship. That was the state before all the deregulation. Laws were the things enforcing "tightly sealed compartments". Now the laws are no more and the ship has sunk.

Now I challenge you as an individual to keep your face straight while you defend "deregulation" and Wall St. after all that has happened.
