Questions I have about the financial crisis.🤔

All of the following questions are ones that I want to ask about the financial crisis:

• Was anybody actually at blame for the financial crisis?
• Why did the Chancellor at the time (Alistair Darling) choose to give money to to the failing banks instead of things like Education and the NHS?
• Was it actually necessary for the banks to take all those risks?
• Did smaller countries get affected by the financial crisis? If not, why?
• How was the financial crisis dealt with?

Feel free to answer any of the questions.
