It just strikes me as yet another fuck you to the poorer people. They don't get to go on holiday, but the wealthier do.
Look at prices during the school summer holidays - it is usually 2-4x higher. Poorer families can't afford that. I think it's beneficial for families to be able to occasionally have some respite from work/school, and do things they wouldn't usually do.
The least they could do is stagger the school holidays so that you don't have 90% of the UK taking them all at once.
There's an unbelievable amount of class warfare in this country.
