The development of artificial intelligence meant that machines took over 95% of jobs. Extreme inequalities have arisen around the world. After years of brutal transformations, the interplanetary federation has established a global basic income. The main currency became the energy that powered the robots that produced food and all other goods.

Even a handful of intercaste marriages have resulted in a legal demotion to the higher born partner.
