Yes, it is! See, the US has one of the largest income inequality gaps in the world, for a developed country. This is bad, basically because that wider the gap becomes, the more people live in poverty. You can see many problems increase in unequal countries - more teen pregnancies, more obesity, more incarceration rates, and more bad grades. Many economists also say that income inequality slows economic growth - because the middle class is shrinking and the number of impoverished people is increasing, it means that there are less people working in dynamic industries. Inequality weakens a country's middle class, shifting everyone into the lower class. The middle class ends up not being able to support the economy, which leads to economic slowdown. US economic growth has averaged 2.2%, which is a whopping 1.1% less than our usual average. This is all because of inequality.
