Cameron speeches, Islamic extremism, Corruption etc.

The short-termist, headless chicken-ish style of government you describe probably does fit in with the mood and circumstances of the day.

I'm afraid that's the way it is for the present. We may have had inept governments in the past but at least they did tend to get things done despite being full of extremists and closet paedophiles as some of them were. Nothing - I repeat - Nothing will get done properly until we sort out whether or not we are going to remain in the 'Club'. Business will continue to trot along making contingency plans for a withdrawal, should that occur, and likewise under-invest for the short term.
We need to settle down. It's either more crap and go along with the flow or kick out the wasters and fence-sitters and drop into fast gear for a new world trade future. The choice is yours and yours and yours and yours - for those who are remotely interested - which sadly most aren't.
