Until people are affected by inequality most will not give other peoples problems a second thought.
With the media avalanche of how it could all be lost by voting for any party other than the conservatives the vast majority vote for them.
The amount of people who said to me they couldn't trust Miliband, just look how he treat his brother, is another issue that gave the Tories a boost.
Also those who took in the polls that it was neck and neck were panicked into voting Tory. I work with a lot of ex miners and steel workers and the offspring of miners and steelworkers and most of them told me with no uncertainty they were voting Ukip cos Labour didn't care anymore. When I said vote for TUSC then I was told it was a waste of a vote because nobody would notice. Plus I got told to fuck off to Russia by some, that's how on the ball most workers are sadly.
