GLOBAL FINANCIAL CRISIS.

The main cause was the financial instrument, that pool their various loans into sellable assets. This method would made a great disaster for banks because they will be tried up for decades. This risk was named the greatest financial innovation in the 20th century. This starts in Wall Street and then in all the world. 

This situation was: Banks borrowed more money to lend out for have more securitazion, When their securitazion became a bad loads, they sell to banks, and this was not their problem yet.

When they did not borrowed to other banks, they turned to the poors (the normal people). As the houses' price raised, they thought that these bad loans would make recuperate their high-valued property. Many banks were taking on huge risks increasing their exposure to problems. 

The problem was so large, even the banks with large capital reserves felt into ruin. so they had to turn to governments for solve this large problem. 

Shrinking banks caught all the money of the economy, because they intented to have a large capital and became the biggest bank in the world. But, businesses and individuals that borrowed to banks, they find difficult make money to solve their credits. 

SOLUTIONS

The banks would think more about how much borrow and lend out, to who lend money, and have a large capital bit by bit, not at the moment. 

And the businesses and normal people would think more about how much borrow from banks, and if they could pay all the money. 

In my opinion, she has so much reason, but I think the banks could not to have a large capital of goods, they would have a lot of money to "play" with it and make the world more easy. They would not to be so selfish, and think more about the normal people.
