Interesting and relevant project. Learning a different language besides our mother tongue is vital: to become aware of other language singularities; to rise our QI; to become interested in other cultures and to potencially have more oppportunities to work and live abroad. At least in theory. I'm sure speaking two languages is an advantage for everybody, but I believe providing kids with other tools besides languages, has more benefits. I'm Portuguese and I live in Portugal. Here, everybody has to learn at least two languages besides Portuguese in school. We all speak Portuguese, English and a third one: French, German or Spanish. Although, in Portugal it is almost imposible for a common citizen to afford living or studying abroad. I believe that teaching kids how to be more competitive, proactive, how to discuss general topics in school and with friends, are key elements for rising their opportunities to become more successful professionals in the future. That's great to speak 2 or 3 languages and feel confortable when traveling to the US, England or other country (because English is the trade language everywhere), or going to Brazil and speak Portuguese there, but if people don't have other social and professional tools to complement languages, opportunities won't happen just like that.
