The fact about the matter is that English, American or British is needed around the world to do business... the reason that the majority of welsh speakers learn english is to better their chance of getting a good career, as they have a better chance of getting a higer paid job in one of the big three english cities, London, Manchester, Birmingham...
Welsh is a language that most people could live without in this country, but I dont think vice versa... I know that if I only spoke welsh I would not make as much money as I'm earning now... calling suppliers that all speak english... English language dominance extends from both the british empire, as it use to be, and now through American Dominance as the number one world power...
Welsh is having such a surge due to Welsh pride, and the fact that there are small pockets of Wales that still do use the Welsh language as their first language...
