The film Inside Job takes a look at the financial crisis of 2008. It documents the systemic corruption of the United States by the financial services industry, and the consequences of that systemic corruption. I strongly urge you to watch this if you can spare the time.
It takes nearly 2 hours but it is in 15 minute chunks and even if you only watch part of it I feel sure you will find it worthwhile. The greed, the lies, the corruption is so rank and did such terrible harm and caused such terrible suffering worldwide, the perpetrators should not remain unpunished and should not still be in positions of power - but they are still in positions of power! The Law has supported and protected these wicked people.
If you are one of the people who has suffered because of the financial chicanery of the banks and the useless regulators, venal politicians, etc. - and that is surely all of us - I do urge you to watch this film and see how easily and cynically it was done.
The price of freedom is eternal vigilance. I believe these horrors will happen again because the fraudsters/criminals are still in power - still raking in shedloads of cash - still robbing the poor of all lands.
Please try to watch it!
