I am sure I heard something on R4 today about the age people start voting Conservative has moved up to 63. There was a young Conservative bemoaning the fact that the current lot seem to be still pitching to the older voter whilst completely ignoring the concerns of the younger voter, especially in regards to housing, starting a family, childcare etc.
The problem with focusing on a fringe issue like public schools, is that the vast majority of the electorate don't use them, and believe that those who do are relatively well off, as in earn two incomes above minimum wage. I appreciate that there are those who's children have managed to secure a scholarship/bursary who are going to find it difficult when fee's go up again as they are apt to do, and tend to do every year if the truth be told ! I suppose Public schools could support those students by increasing the fee's for the parents who do pay the full amount ?
