To me it is not even about being able to afford it or not.
I really object on principle to spend that much money on something like this. I just picture all these blase teens, who have been to far flung places yet never seen Wales or Scotland or historical sites in England.
Visit the UK, then Europe, it is sad if that is seen as " not exciting enough", as there is much to see and do.
People can go to faraway places once they are a bit older.
Having lived in South America, I would seriously worry about the busloads of spoilt western teens ( who do not even know they are spoilt) with their Nike shoes and logoed clothes, flashing their smart phones... In Peru a few visiting school buses were held up at gun point in recent years.
Sure, teachers read up on safety, but if you have never lived in a third world country it is hard to grasp the level of poverty, and the extravagant value of a pair of branded trainers to the poor and/ or criminal minded. Let alone the smart phones all the kids carry along, which are unheard luxuries and worth the rob someone for, let alone a busload of kids with them.
Ludicrous, these trips.
