This is quite interesting. Keeping in mind that social grade is a bad proxy for class, something has happened to voter alignment around redistributive policies.
(1) hypothesis one: realignment + partisanship. Voters instinctively identify the policy as a pro-Labour, anti-government proposition and react to it according to their partisan priors, which have become a lot less class-based than before.
(2) hypothesis two: social values. Via education, social liberalism is now prevalent among the rich, and it informs some aspects of economic attitudes: i.e. redistribution directed towards a & #39;deserving outgroups& #39;. Plus it comes with higher awareness of social desirability.
(3) hypothesis three: the specific politics of free school meal. Because the measure is not immediately linked to taxation and macroeconomically trivial, there& #39;s a lesser & #39;selfish& #39; dimension to it. It is informed by values of non-economic nature, rather than economic interest.
(4) hypothesis four: age distribution of occupations. Because younger adults are more likely to be parents than the elderly, and the former entered a job market with more & #39;ABC1& #39; jobs than & #39;C2DE& #39; jobs, there are actually more financially insecure parents as a share of ABC1 voters.
(5) hypothesis five: this is a subgroup analysis of one poll, which uses a questionable social grade measure, so it& #39;s virtually meaningless.
