Our primary school offers extra curricular clubs in sport, dance and music at £2 per person for an hour for a class of 20 children. A local languages teacher charges £7 per person for half an hour for a class of 8 children. Some parents won't be able to afford the language classes because they are so much more expensive. Assuming there is sufficient interest, is it unreasonable to suggest that the school run the course for those children whose parents can afford it? Or does that seem unfair?
