Thankfully this is a minority opinion and also mostly redundant, since most swedish people of working age speak and write English well enough for business purposes. There would be no benefit and a huge cultural heritage would be lost. Young swedish people need no extra motivation to learn english - they pick it up naturally from globalized media anyway, a lot faster than we can teach them.

The way the world is heading, it would be better to make German, French and Spanish mandatory in school instead.
