Income inequality is the fault of the individual. Dropped out of high school and work part time at a coffee shop?... Don't expect  earn an equal income as someone who works 6-10 hr days, sacrificed  to start their own business, or went to college for something other than a liberal arts degree...       Work hard, Save, and quit worrying about what the other guy has.
All men are created equal,.... but not gaurenteed an equal outcome...
