I clicked the clap button, this is an interesting idea. But be aware that the GINI is not the best measure of inequality. It is convenient, being a singular measurement, but it has problems in both how it is calculated and what it means, and different sources produce widely varied calculations. For this purpose in your article it has its value. But most of the top economists studying income inequality (Saez, Picketty, e.g.) tend to focus more on classic measures like shares of the top X percent.
