In the journal Political Insight, a team of authors published a summary of the research on British political culture. Their study investigated whether political culture fosters specific social attitudes over the long run. Whilst their results reveal some interesting correlations between longitudinal shifts in attitudes and potential changes in political culture, some findings from the British Social Attitudes Survey can also be read with Miliband's claim about shifting views on economic inequality in mind. The figure below shows the responses stratified by age of respondents and year of survey to the question: 'Thinking of income levels generally in the UK today, would you say the gap between those with high incomes and those with low incomes is (1) too large; (2) about right; or (3) too small?'
This has also implications for the campaign of the Miliband camp. If income inequality does not appear to be a major concern of people in Britain, it is unlikely to be a major motivating factor to vote either.
