I know I think learning Chinese is good, but:
BBC: An increasing number of families in the United States is looking to employ Chinese nannies - not so much for their child-rearing abilities, but more for their language skills. Parents always want to give their children a good head start in life to prepare them for the future. It seems that families in the United States with a lot of disposable income believe that helping their children master the intricacies of Mandarin at an early age is one way to do that.
JaNiece Rush explains that they are in such high demand they can command a salary of around $20,000 more than the average nanny would earn. One Chinese woman even managed to secure a salary of $70,000-a-year after two families tried to outbid each other to get her.
