This effect holds true regardless of a nation’s wealth, culture or political system, but its intensity varies from country to country. In China, a child whose parents own 500 books will average 6.6 more years of education than a comparable child from a bookless home. In the U.S., the figure is 2.4 years — which is still highly significant when you consider it’s the difference between two years of college and a full four-year degree.
Of course, there's definitely an income stratification component to the finding—probably in all countries. But, it's still nice to know that reading is fundamental. I'd just like to see how the Internet and e-books will impact this finding down the road.
