What
 Maliki chooses to ignore and what Ban Ki-moon has singled out is 
precisely what the protest movement has been demanding all along: 
looking at the root causes of the problems. In Iraq's case, they are 
sectarianism, corruption, lack of basic services, violations of human 
rights, increasing unemployment and organized gangs and militias 
flourishing under a kleptocratic government.
The Maliki government has been harvesting over $100bn a year
 for some time now, from the nation's oil wealth. That amounts to about 
$20,000 a year per average Iraqi household of 7 people, except that 
Iraqis are left deprived of basic commodities. The wealth is squandered 
or stolen, a situation illustrated by Transparency International
 as: "Massive embezzlement, procurement scams, money laundering, oil 
smuggling and widespread bureaucratic bribery have led the country to 
the bottom of international corruption rankings, fuelled political 
violence and hampered effective state building and service delivery."
