And wealth is not a Lake. It does not run dry. You can create wealth. If wealth could not be created we would be super poor by now with 7 billion people on the planet compared to 100 years ago. But it's the exact opposite, we are hundred time richer than 100 years ago.
When everyone earns a little more than before over time, there's not so much cause for social unrest. Countries with growing economies tend to be more stable and peaceful Revolutions occur when people get poorer and lose hope for a better future.
I never said it is a like a lake. I meant an actual lake. Lake was example how inequalities lead to richest people making policies that don't impact them. That is the biggest threat income inequality may present to any society.
Money is like gravity/mass. The more money you have the more money you attract. You may create wealth, but if you don't distribute it, some points may gather too much like their matter counterparts, turn into a black holes and consume the reality around them. It's like that man that asked Ford "If you don't give money to your workers, who's gonna buy your cars?"

Wait, what about Brazil and Turkey? Aren't they growing economies? Why are their in state of unrest?
You can drain a lake for thing X until your lake runs dry. Who is least susceptible to change? Those with money . Either they move or they buy water).
The high Gini coefficient correlates and probably causes so many bad effects it shouldn't be ignored. It's not the one and only measure, and there are other important measures but it is a very good predictor of social unrest.
