Economics of the Future

So I was somewhat shocked the other day when I saw that Dell still employs around 10k people in Austin, but only around 70k people worldwide. Which is crazy when you realize they’re number 34 in the fortune 500. FoxConn out of China who manufacturers a lot of the products for Dell, Apple, etc. has 800,000 employees. Over ten times as many employees as Dell. I just wonder about this. If you can do only the most profitable work with a small number of employees, what’s your long term business plan? What’s to keep FoxConn who can actually make things cheaply and easily from getting into the managing people who make things market?
