The least unequal countries from the time they started measuring GINI have had a value between 0.250 and 0.300, including the likes of the Soviet Union which was on the upper end of that range, and many former eastern block countries alongside Scandinavian countries who are currently at the lower end of that range. Note that these values are after taxes and transfers. I think the goal, especially within an economy modeled loosely around capitalist principals, should be to have a low GINI prior to taxes and transfers, something South Korea can claim to have one of the lowest in the world at around 0.350 and they've had some of the fastest economic growth on earth over the last couple decades, in addition to having one of the most highly educated populations on earth, especially among young people. They also invest the highest percentage of their GDP on R&D. Switzerland, Norway, and Denmark also still have one of the lowest levels of inequality before taxes and transfers at around 0.400. As such you have created a much more stable society, where you do not divide society into groups who either are deeply concerned about inequality or feel as if they are being taxed too much.
