Ever since I started blogging in 2009, I’ve been predicting that China would become the world’s largest economy, and much faster than most people expected. If you’ve been reading the news, you know that it has already happened. But I also made a more outlandish claim, that India’s economy would soon be as large as Japan’s (a country with exactly 1/10th India’s population), and that in 100 years India would have the world’s largest economy.
