Baltimore riots are a symptom of income inequality:
Baltimore's inequality gap:Driven in part by globalization and technology that have wiped out jobs, income inequality is a mounting problem around the U.S. The issue is particularly acute in Baltimore, the biggest city in the country's most affluent state.
The median household income of African-Americans in Baltimore is just $33,610, compared with $60,550 for white households, according to the U.S. Census Bureau.
Even more dramatic, the unemployment rate for young black men between the ages of 20 and 24 stood at an incredible 37% in 2013, compared with 10% for white men of the same age group. Moreover, nearly 24% of Baltimore's population lives below the poverty line.
"We have to deal with this gap because if we don't deal with it, eventually the biggest political problem is not going to be a geopolitical problem from the Middle East or Ukraine, Russia or Asia, but will be domestic," Roubini said.
