You can say it's a good thing that an ancient language and corresponding culture is being saved (although I would also argue that draining Welsh speakers from their familial localities by proving strong financial incentives to move to Cardiff is ultimately doing huge damage to the cultural heartlands of Wales), but I can't agree with this statement. Census data shows that Welsh language usage has decreased slightly over the past 10 years, and Welsh-language schools (funded at extra cost to taxpayers as a parallel school system) do not perform as well academically as mainstream schools. Sure, everyone here has done a Welsh GCSE, but it's largely considered a joke and kids boast about how little they learned.
