<p>Even though the majority of the Americas speaks Spanish, the language is more widely used in ground level business worlds, mostly raw materials, manufacturing, the agriculture and textile industries. And if you are working for high-tech companies then knowing Spanish is almost useless. Because of the number of people who can speak it, hiring a really good translator is quite cheap. </p>
<p>Ideally you’d learn Mandarin and Japanese, but those are difficult for people whose native language is Romance or Germanic based. And even if you acquire them, there will be nearly 2 billion people in the world who already speak them, and they’re way better than you. And just knowing the language of those countries isn’t nearly enough to really understand how business works there. Your understanding of Oriental culture will always lag far behind the native people there. </p>
<p>So for the best use of your time and results, I’d take up French, Russian, or Arabic.</p>
