To learn languages is very important because guarantees best chances of job and best salary.
In Brazil, usually the Spanish language it is teach strating on higher elementary education and the English language on high school.
There is a question: why just 5% of the Brazilians speak another language.
I think the teach of languages at schools is good, but, insufficient to the students become fluent. Very teach of grammar and some conversation. That is not good. It is need to teach also more conversation, thus, the students can develop more and best. Also it is need interest of the students to learn another language. It is need appointment with the language.
