I heard that briefly on Radio 4. The man is deluding himself!! Whether he likes it or not, English is the common language around the world; the one which, as I understand it, is one that people most choose to learn apart from their own, since they know it will enable them to communicate with most other people travelling around the world.
Those who do not study another language, and equally important, some of the literature of that country, are missing something I think, as it is not quite the same as reading translations.
