I would imagine that there is less than 1% of people under 50 that speak Romansh natively that don't speak another language fluently, most likely Swiss-German, but also English. With the huge amount of homogenization of culture around the world, I think its cool if some corners try and keep some differences. These Swiss are surely not suffering in some backwater area, unable to move to the big city if they want.
