When someone like Bill Gates comes with advice to nation, he/she is not beating a drum. It is an out cry that better be taken seriously. He is not talking in personal interest or company's interest (if MicroSoft wants, it can employ thousands in India without worrying about Visa), he, in my view, is genuinely talking about nation. Though I have much limited view of things than what Bill has, I share his concerns. US need to wake-up before the center of gravity shifts away.
