Knowing a foreign language isn't useful to some people. For example, if you can't afford to travel or aren't interested in visiting other countries, you might never get to speak the language with natives. In addition, although speaking a foreign language makes traveling more fun, it's easy to get around in many countries while speaking English. Knowing a foreign language is a prized asset in some careers, but it's not helpful for many jobs. And some foreign languages, such as Latin or Ancient Greek, aren't even spoken anymore.
