Since the global financial crisis and recession of 2007-2009, criticism of the economics profession has intensified. The failure of all but a few professional economists to forecast the episode - the aftereffects of which still linger - has led many to question whether the economics profession contributes anything significant to society.

People who stay unemployed for a long time start to look like damaged goods, and they don't get such good offers. Also, they're not learning anything. Most learning is on-the-job learning.

If we wait until income inequality is much more severe, we will have a whole class of new superrich who will probably feel entitled to their wealth and will have the means to defend their interest. That's already gone far enough. We shouldn't let it become more extreme.

One thing I've noticed about history - you can search on newspapers going back hundreds of years, search for 'economic forecast,' you don't find it. It would be very rare to find it.
