There would be no difference whichever party was in power. Every party is out for what it can get from the great british public. How many poor politicians do you know? Corruption is rife at every level.
Every government ruins some things and makes other things better. They change things for change sake. They have committes to decide which committes we should have to make decisions that the rest of us have to put up with forever more, because once they change some things, they can never be put back the way they were.
It is the blind leading the blind into a state of utter chaos. None of them know what the hell they are doing anymore (if they ever did!).
