Seeing the wood for the trees?

It seems more and more parents are taking their children out of school during term time without permission to take advantage of the cheaper cost of holidays at those times. All political parties have united to deplore such behaviour, and to demand that such parents be held to account. Classic case of treating the symptom as though it were the disease. They should be concentrating their attention on the tour companies and holiday industry generally and asking them how they can justify the identical holiday on a particular week costing anything up to double what it did the week before, simply because the week in question is a school holiday week.
