There are many reasons to learn Mandarin Chinese.
For our kids (we are all native Mandarin speakers and our kids were all born in the United States), we want them to learn Mandarin because of 1) Chinese culture and family connections, and 2) the emerging Chinese economy.
Here are some reasons that might resonate with you:
First of all, Chinese Mandarin is the most widely-spoken language in the world. In addition to the mainland China and Taiwan, Mandarin is also spoken in Singapore, Malaysia, Indonesia, Thailand, Brunei, the Philippines, and Mongolia.
Moreover, Mandarin is one of the fastest growing foreign languages taught in the United States. According to national research, there are more than 200 Mandarin dual-language programs in K-12 schools, where students learn in both Mandarin and English.
Thirdly, China is the second largest economy in the world and still one of largest trading partners of the United States.
Last but not least, Chinese is a symbolic language that helps English-speaking kids develops the artistic part of the brain.
