Switzerland is a rich country, and just about every ski resort is outrageously expensive (think 14 euro for a beer, 35 for a pizza, 150+/night for a hotel, 50+/day slopes). So financially, they can definitely get away with helicoptering in snow.
The most exclusive ones are probably St. Moritz, Zermatt and Lech, not so sure about Gstaad.
