I have had the pleasure of meeting professor Tyler Cowen a few times and always left my meetings impressed by his intellect. He writes the popular economics blog: Marginal Revolution.
He just wrote a great article for the New York Times on how technology could help fight income inequality. He specifically focuses on the potential decrease in health care and education costs that automated diagnostic systems and online education could bring. He also speculates that general worker productivity could increase as computers become simpler allowing more people to work with them. China and India might also start generating new ideas particularly targeting their large number of low income individuals, thus providing new solutions for the West’s low income individuals.
In many way his article is reminiscent of my case for optimism and I find his arguments compelling and convincing. It is well worth the read: http://www.nytimes.com/2014/12/07/upshot/how-technology-could-help-fight-income-inequality.html
