H1b's are for skilled workers who already went to college in their respective countries. So you can take universities out of the picture. In terms of companies, think about Uber, Amazon, FB, etc. They're huge right? Well, India and China have their own products. It's hard for US companies to gain market share in Asia because people already use local products! Last but not least, you don't have to make 2.5 billion people rich in order to become the number 1 Tech hub in the world. All you need is a tiny place like San Francisco bay area.
