Learning Spanish in school was the single biggest waste of time. 14% of the country are native Spanish speaker! Many professions require some spanish! Those were the arguments back then as well.

However... unless you account that the native speakers and heritage speakers will learn English, making your ability to say cerveza useless. If you aren't fluent and have professional Spanish qualities (like Medical Spanish), its useless. Learning Latin or Greek would have been more useful, at least I could struggle through Cicero in Latin, than saying 3 words in Spanish before the other guy switches to English.
