Of all developed countries, the United States is the one losing the most money because of illiteracy, and more than half of its adults read at or below a 12-year-old’s level, a new study shows.
Low literacy skills likely cause mistakes that cost the United States about $300 billion every year, according to a report released in September by the World Literacy Foundation (WLF). Overall, the developed world loses about $803 billion to illiteracy every year, according to the study.
