Sometimes a chart explains it all and this is the case with this chart showing income distribution between the rich and the poor in the US demography. 5% of top rich class continues to earn more and more money while the remaining 95% earnings are almost static over the years. For further interpretation of the income distribution you can refer to the source at Marketwatch.
In a recent conversation with some friends and colleagues the same topic came into discussion not only from a US region perspective but in general cross continents' standard of living perspective. Does the above 5 to 95 distribution of super richness to richness/mediocracy holds across other regions? Leave your thoughts / feedback with your experiences in the comments section.
