Yes, I do think that there has historically been a social class litmus test element to skiing. I am well spoken (but not from a wealthy background) and spent my university years and early twenties being asked two questions at almost every social occasion:
‘Where did you go to school?’
‘Do you ski?’
I suspect that my frank and honest answers confused many people who were assuming that I was ‘one of them’!
Given that the ski-chalet holiday experience was originally modelled on the English country house weekend and, in the eighties, there was a virtual conveyor belt taking nice-but-not-too-bright-girls from boarding school, to Leith’s cookery school, to a season as a chalet host, to a marriage with one of the ‘right background’ guests, I think it is naive to think of it as having anything other than upper middle class origins. Doesn’t skiing feature in the Sloane Ranger Handbook for god’s sake? ;)
There is a rather funny BBC documentary on YouTube about the early days of skiing holidays. It seems to intentionally draw a comic comparison between the ‘to the manor born’ plummy-voiced confident skiers and working-class Rita, Bill, Bob and Sue (not real names) taking a package holiday and then mucking it up in magnificent style the first time they get on a ski lift.
My DH and I learned to ski in our early thirties and have been numerous times. He is an expert skier, our DC is good and I have reached a point where I can ski most blue or red slopes but don’t think further improvement is very likely!
The internet has democratised skiing to a certain extent. But it is expensive and I still think it’s something that you need to invest a lot of time and money in before you get to the point where it is truly enjoyable as a family holiday.
