Anyone who gets surprised when they find out someone has never been skiing.
That depends on culture a lot. In Austria it’s actually rare to find someone who has never been skiing (25% of the population go skiing regularly, and that has already been at around 50% not many years ago). Even when not doing it with your family while growing up everyone learns it at school.
I’m not rich at all but I do get surprised when someone who isn’t obviously from another country has never been skiing (typically it means that they grew up somewhere else but you just don’t notice anymore).
Sounds like a good way to afford your hobby, but nothing you can live off when having to compete with big players like refurbed that can outsource the work to low wage countries.
