After a number of back and forth iterations, the one that was ultimately decided upon was a simple allegorical image depicting ladders and star-bearing trees as a metaphor for inequality. The thinking was to present the subject as being more about inequality of opportunity and not so much about class conflict. Due to exclusive copyright issues, I'm unable to show the final image, but one of my initial rough sketches, which I used as inspiration for this image, was seen as putting too much emphasis on the "99% vs. the 1%" for this particular assignment.
Now, given the recent headlines about California's mega-drought, it's taken on a more literal meaning. Gov. Jerry Brown's conservation and rationing measures are already being criticized for giving unfair breaks to big business and the oil industry in particular, whose fracking technology uses tremendous amounts of water for an already controversial process. Solutions for now involve conservation and shared sacrifice, and praying for rain. In the long term, growing and engineering crops that require less water, and improved desalination and groundwater drilling techniques may help. Given the fact that nearly half of the nation's produce is grown in California, it's a problem that will eventually affect nearly everyone in the U.S., most of all those who can least afford it.
