"Everybody at a very base personal level has fear and mistrust of others and likes to blame others for perceived predicaments"

You've got it wrong there old boy. Mr Farage does not blame the immigrants, I have heard him saying that he cant blame anyone from leaving a bankrupt, basket case of an economy, to come to a country where they can earn and send money back to their families.
That is simply self interest and self preservation.

Mr Farage blames a series of UK governments, for following a media, and short sighted economic agenda, which caused all the social and cultural predicaments.

Remember how UKIP was demonised by "liberals"? Their agenda has been scrutinised and found to be flawed......Surprised?

You want a capitalist economy, you must be prepared to exploit everything and everybody......but you must be sure you have the infrastructure to carry it off.   :0)
