If there’s anything close to a law in sociology, it’s that young people don’t vote. So what you’re saying doesn’t feel particularly specific to the U.K. One thing one might argue for would be a political system where old people’s votes are discounted (because they will die soon or because they are ‘over represented’ due to their bothering to vote).

I guess one could also make arguments about the structure of the system which feels a bit more specific to the U.K. eg rural–urban constituency differences or FPTP.
