This documentary was one of my main inspirations. It also made me realised how badly informed I had been by the mainstream media. This documentary was shown by the BBC although it was made by an independent company about 10 years ago. It may help put some things into perspective. Note that most of the organisations mentioned - Conservative Party, Freedom Association, Institute of Economic Affairs - still exist but are pretty useless nowadays and can't be relied upon.
This is another one shown on Channel 4 soon after the 2008 financial crisis.
