Income inequality? As I wrote in a comment above, Income inequality is in some sense, a lot worse than wealth inequality. It means that the fruit of growth is divided in a way that the lower half gets a substantially lower cut. This means that wealth disparity can only grow.

Think of startups gradually removing stock options from their employees, until they are absolutely eliminated with no salary compensation. Shareholders and management will get all the big gains from the company growth. One could consider this reasonable if the separation of dividends corresponds to the value provided, but I'd argue that there is a difference in the value you create, and the ability to capture that value.
