Both Fair And Balanced
That is a gross oversimplification. It varied considerably from country to country. And in the US, it even varied radically from state to state until the early 20th Century.The children of Europe weren't educated because they were busy working, same in the USA.

Much of the problem was due to totally inadequate public education in many of these countries.
The Beginning of the Public Education System
Until the 1840s the education system was highly localized and available only to wealthy people. Reformers who wanted all children to gain the benefits of education opposed this. Prominent among them were Horace Mann in Massachusetts and Henry Barnard in Connecticut. Mann started the publication of the Common School Journal, which took the educational issues to the public. The common-school reformers argued for the case on the belief that common schooling could create good citizens, unite society and prevent crime and poverty. As a result of their efforts, free public education at the elementary level was available for all American children by the end of the 19th century. Massachusetts passed the first compulsory school attendance laws in 1852, followed by New York in 1853. By 1918 all states had passed laws requiring children to attend at least elementary school. The Catholics were, however, opposed to common schooling and created their own private schools. Their decision was supported by the 1925 Supreme Court rule in Pierce v. Society of Sisters that states could not compel children to attend public schools, and that children could attend private schools instead.
High Schools
The first publicly supported secondary school in the United States was the Boston Latin School, founded in 1635. Harvard was the first University in existence at that time. The attendance in secondary schools was very little because the curriculum was specialized and hard. The demand for skilled workers in the middle of the eighteenth century led Benjamin Franklin to start a new kind of secondary school. Thus, the American Academy was established in Philadelphia in 1751. American high schools eventually replaced Latin grammar schools. The rise in American high school attendance was one of the most striking developments in U.S. education during the 20th century. From 1900 to 1996 the percentage of teenagers who graduated from high school increased from about 6 percent to about 85 percent. As the 20th century progressed, most states enacted legislation extending compulsory education laws to the age of 16. It is essential to look at the history of public education along with the events shaping the country in the early years of the 20th century. The Great Depression, World War II, the Cold War, wars with other countries, civil rights movement, student protests and the numerous political events within the country all had their effects on the education system too. In the 1920s and 30s, “progressive education” was the word of the day; the focus then shifted to intellectual discipline and curriculum development projects in the later decades.
