It's nothing new. Way back in the dark ages when I was in the 6th form, a trip was announced to Russia. This was when nobody went there, it was all mysterious, and everyone was advised to take several pairs of Levis because they could sell them for loads. Only one girl from our class could afford to go. Oddly the rest of us just accepted the situation and went on our French and German exchanges which just cost the ferry fare. I much preferred that to something like a week on the train, then another week home again. We really liked the tales Sheila brought back with her, but I don't remember any feeling of 'them' and 'us'.
