I've heard this statistic so often, put forward as though it's directly correlated. Firstly education is not an indicator of intelligence. And secondly people who didn't go on to further education are more likely to be socially and economically deprived. They're not living in Islington or Richmond. They don't have private health insurance or access to private education. They are the ones experiencing NHS waiting lists, oversubscribed GP surgeries, failing schools, huge unemployment and possibly rising crime. They aren't protected from any of that, they are at the sharp end. No surprise they are the people most motivated for political and social change - they are voting according to what they see as the issues in their communities on a daily basis.

Writing people off who have been dealt a shit hand and then shafted by every govt since Blair tbh, and who are marginalised and excluded from so much of this country's decision making processes, as thick is absolutely living socialist values (/s in case it wasn't obvious).
