As for the UKIP party, their words sound good. But like any other party (never mind the Red or Blue) that would get in power, once in then the wheels come off the vehicle quickly 
I'm as cynical about politicians as you, but UKIP does not consist of a majority from the "political classes". Whilst I once clashed with Banjax over his Eton-educated criticism of Cameron, I am now beginning to see that there was an element of truth in what he was saying. Not the "Eton" background specifically, but the old pals' act - the naked nepotism - that surrounds those who have never had a proper job and have had the goal of becoming a politician ever since they got out of nappies. They achieved their goals by knowing the right people, not by ability.
I sincerely believe, or I would not lend them my support, that the majority within UKIP's ranks are genuine people - and for whom the word "Bilderburg" is an obscenity.

I don't think they would let us down, were they ever to achieve power. However, I appreciate we're not talking science here, so it cannot be a certain fact.
