Just a random thought. U.S.A. designs high tech stuffs, China assembles them, and Hong kong buys them. In a way, Hong kong is sitting at the end of the value chain. So U.S.A. gets all the technologies and money, China gets all the investment and jobs, and Hong Kong gets iPhone….But they were sold back to China, with a much higher price. Hong Kong needs to be technology driven, and sell the products to mainland China. Look at the high-end service they provide for China currently, people in China are doing exactly the same now, but cheaper (accounting, marketing…) When I watched on them in the business news , a lot even say the other way round to enter the Hong Kong market.
