Mexico DSO Average 67 Days Best Possible DSO 51 Days ICTF Conference Mexico DSO Average 67 Days Best Possible DSO 51 Days Average Days Delinquent 16 Days Past Dues Average 16% Competitiveness: Competing against the BRICS bloc (Brazil, Russia, India, China) for economic opportunities, markets and foreign investment from developed countries. Security: The ever-scaling violence between drug cartels and police forces, as part of the "Mexican War on Drugs". Also, inadequate funding has allowed for high levels of corruption among police and armed forces, specially when dealing against drug cartels. Education: Lack of education for most of the population (only one in every 10 Mexicans completes college education). Also, the public education system in Mexico is one of the worst in the world, but any attempt to reform it is blocked by the National Teacher's Syndicate, which by the way is one of the most corrupt in Mexico (just second to the Oil Workers' Syndicate). Economy: World economic bust compounded with a swine flu (H1N1) scare is keeping a depressed economy: the high dependence on America as receiver of Mexican exports as well as source of international tourists have impacted negatively on the Mexican economy to astonishing levels (-7% of growth during 2009). Poverty: Although Mexico is a world leader in hunger reduction, there is still a 5% of children under 5 suffering with malnutrition; according to the United Nations Development Programmed, 17.6% of Mexicans (19.7 million for 2009) are below the poverty line. Peak Oil: Current Mexican oil reserves are dwindling, with 8 years left to be completely gone. Corruption: Rampant corruption among public officers
