Pucky the Whale

Here, let me help:

Bankers gave loans to people who couldn't pay it back.

Bankers put property of said person up for mortgagee sale when said person couldn't meet loan.

Banker couldn't sell property for value of over inflated loan value so lost money.

World went into recession.

Governments gave banks money so the lending managers could buy themselves more flash cars and bigger houses.

World stayed in a recession.

The end.

And whatever you do, remember you spell bankers with a "w".
