> GNI is just a grand total divided by population;
Right, per capita, as I stated, but really just GNI is fine too.
> people would be making more if the money was divided up evenly but it's not, particularly in the U.S
Unfortunately the google public data didn't have enough US data but take a look at these two charts for India.
First is just India's per capita GNI the second is India's income distribution over the same time frame. Notice how the income distribution is relatively flat and how the GNI is growing.
