Economic Development in India and China vis a vis the UK and USA

 Hans Rosling on the rise of China and India over the years. Witty, interesting and a simple take on the linear data involving growth in life expectancy and per capita income. He manages to illustrate how political changes affected these two development indicators and how things are expected to pan out. The key points to be noted include the impact of war on the economy and how  skewed economic growth can be a dampener.
