If you're considering going to work in China, and wondering if you should learn Spanish instead of Mandarin, what are you doing. If you're trying to get a promotion in a Spanish-speaking company and considering learning Mandarin instead of Spanish, what are you doing. If you're considering learning Chinese or Spanish for utility, it seems extremely unlikely that they would lead you to exactly the same opportunies; if you can't tell which would lead to better opportunities AND you can't tell which you have more interest in, that suggests you don't have much utility for either, much interest in either, and should do something else more immediately beneficial instead. e.g. skills training for a specific promotion at your place of work, or sought after skills in your local job market. If you're considering learning anything for fun or interest, then learn the thing which you find fun or interesting, not the thing which internet people tell you that you "should" based on something so completely irrelevant as how popular it is. Keeping up with the Jones's is a mistake, not a desirable way to live.
