“Rising income inequality has set off fierce political and economic debates, but one important angle hasn’t been explored adequately. We need to ask whether market forces themselves might limit or reverse the trend.
Technology has contributed to the rise in inequality, but there are also some significant ways in which technology could reduce it.
For example, while computers have improved our lives in many ways, they haven’t yet done much to make health care and education cheaper. Over the next few decades, however, that may well change: We can easily imagine medical diagnosis by online artificial intelligence, greater use of online competitive procurement for health care services, more transparency in pricing and thus more competition, and much cheaper online education for many students, to cite just a few possibilities. In such a world, many wage gains would come from new and cheaper services, rather than from being able to cut a better deal with the boss at work.
It is a bit harder to see how information technology can lower housing costs, but perhaps the sharing economy can make it easier to live in much smaller spaces and rent needed items, rather than store them in a house or apartment. That would enable lower-income people to live closer to higher-paying urban jobs and at lower cost.”
