This feature, if it could be properly executed, would illustrate the wage gap between the lowest paid worker and the highest paid executives. Submitted salaries (green) would be compared to the estimated pay of the highest paid executives based on variables including (1) yearly earnings of the company (this field could be crowdsourced, for users who want to do some digging online) and (2) CEO-worker pay gap in respective country, state, or other district where this data is readily available.
