I recently mentored two high-school interns at a Fortune 500 tech company. My goal was to give them a real experience in what it's like to work at a big company (code for I had no budget to woo them w/ fancy dinners, concerts, toys, etc.) and to give them real work. They built a useful mobile app. I gave them minimal supervision, directed and helped when I could... based on their feedback I think it was a huge success. I'm glad the company I work for considers interns as an opportunity to train up the next generation of great programmers, managers, and leaders, and practically realizes these people are their next employees. If I'd exploited them as menial labor (getting me coffee, processing mail, doing boring work) they'd lose out and my company would too. Perhaps China has a labor pool large enough to develop and exploit at the same time (that's sad if they do).
