May you live in interesting times.
Ever heard of the GINI index? Basically, it measures just how the poor are and how rich the rich are in relation to each other in any given country (full definition included on the link).

Because you want to be careful investing in, exporting or importing to/from, or starting a business in a country that is about to go up in revolution.
