Why getting children into school was the easy part, and the real crisis is that hundreds of millions are learning almost nothing.
The developing world has achieved one of the most remarkable expansions of education in human history. Primary school enrollment rates in sub-Saharan Africa rose from 52% in 1970 to over 95% by 2020. South Asia saw similar gains. The Millennium Development Goal of universal primary education drove massive investment in school construction, teacher hiring, and fee elimination. Globally, more children are in school than ever before.
The economic logic is compelling. Human capital -- the skills, knowledge, and health of a population -- is the single strongest predictor of long-term economic growth. Studies consistently show that each additional year of schooling increases an individual's earnings by 8-13%. Countries that invested heavily in education early -- South Korea, Taiwan, Botswana -- grew faster than those that did not.
Getting children into school buildings turned out to be the easier challenge. The World Bank's 2018 World Development Report declared a global 'learning crisis': hundreds of millions of children attend school for years but learn shockingly little. In several sub-Saharan African countries, fewer than 10% of students meet minimum proficiency standards in reading by the end of primary school. In India, the Annual Status of Education Report (ASER) found that roughly half of fifth-graders could not read a second-grade text.
The causes are systemic. Teacher absenteeism in some countries exceeds 25%. Many teachers themselves lack mastery of the subjects they teach. Curricula are often designed for the top students, leaving the majority behind. Instruction happens in colonial languages that students do not speak at home. The result is what the World Bank calls 'learning poverty' -- children who attend school but cannot read a simple paragraph by age 10.
The World Bank's Human Capital Index, launched in 2018, measures how much human potential is lost due to poor health and education. A child born in Chad can expect to achieve only 29% of the productivity they would have with complete education and full health, compared to 88% in Singapore. These gaps compound over generations: parents with little education raise children in environments with fewer books, less cognitive stimulation, and poorer nutrition.
Breaking these cycles requires investment across the life course: prenatal nutrition, early childhood stimulation, quality primary and secondary schooling, and vocational or higher education aligned with labor market needs. Countries that have made these investments systematically -- South Korea in the 1960s, Vietnam more recently -- have seen dramatic economic returns within a single generation.
