“Imagine a hypothetical job applicant. He can't spell the simplest words, such as "heal" and "tap". Confused by geography, he thinks there's an African country called "Nambia". As for American history, he's under the impression that Andrew Jackson, who died in 1845, was angry about the Civil War, and that Frederick Douglass, who died in 1895, is still alive.
Given the alarming state of his knowledge, you might wonder what job he could get. Unfortunately, he's not hypothetical, and the job he got, in 2016, was president of the United States.”
