I'd disagree with that view of polarisation daphne - most of us are neither 'toffs' nor 'left behinders' but, as roses said, somewhere in the middle.
What is more noticeable perhaps is that a certain section of society has acquired a voice and is shouting loud and clear 'unfair'. And there are those who are using the genuine 'left behinders' to further their own agenda.
This great divide is a myth put forward by the media, statisticians and certain politically ambitious others, and believed by the gullible, the soft hearted, the bitter and those who blindly follow one political philosophy.
The poor will always be with us, I think someone said. But while the greedy and downright lazy and dishonest seek to take for themselves the benefits that ought to go to the genuinely needy them society will struggle to provide the duty of care we all agree ought to be there.
