@CurlewKate you listed the following things as making private schools luxurious:
nicer surroundings, more activities, more cultural experiences, more wrap round care.
nicer surroundings - very subjective. The draughty cold old buildings appeal to some but not others. Local state school is in a Grade 1 listed building so both sectors have example of new/old buildings. Maybe some have larger playing fields. But again this is a very subjective area.
more activities - yes, but if activities are a luxury then surely out of school activities should be taxed, e.g. tutoring, kids sports clubs, music clubs etc. I can see that some think that anything beyond a very standard one size fits all education should be taxed but I disagree.
more cultural experiences - similar to argument to activities.
more wrap around care - yes, but this is paid for (either by fees or extra charges). Should parents in state schools also be charged tax on the wrap around childcare they use? Again I disagree - taxing childcare would disadvantage working women.
I think that everyone should be clear that when people say private education is a luxury, they are also saying childcare is a luxury, and that children’s activities outside the basic state education is a luxury.
And does this mean that state schools should stop offering any trips/experiences/ after school activities beyond a basic state education?
The local state does more residential trips than the local private school, which are both more than state in the less advantaged area. I assume you would also like to see these type of trips taxed as well?
