Maybe so. But it is always possible to learn a new language. I am STUMBLING my way through learning Italian, and I had Latin and have a degree in Spanish. It stimulates the brain when you bother to learn a new language. I am working hard on pronunciation as I learn the new words. The woman sitting next to me in Italian class yesterday is pronouncing the words like English. She isn't even TRYING. I won't sit by her next time. LOL She kept throwing me off.
Nearly every 7 year old in the world wants to learn English. 95% of the internet and music and tv and the movies, let alone commerce and science are all in English.
The problem is government bureacracy forcing people to do what they don't want to do. Free markets work, just get government out of the education business and all will be wiell.
