Current deficits in health, education, and skill development at work are costing low- and middle-income countries 51 percent of their future labor earnings, according to a new World Bank report. Over the past 15 years, even as incomes have risen and poverty has declined, two-thirds of low- and middle-income countries have experienced declines in nutrition, learning, or workforce skills. Reversing these deficits will require a new approach to human capital investments.
