There is something to be said for humble books like What Every American Should Know about American History. In single-topic history books, the key events are often buried under an avalanche of detail. Not so with books like these, which by their nature must simplify. With simplicity comes clarity. I've found that it's possible learn more about an event from a brief summary than from a 1000-page book.
Besides all that, this particular general history is opinionated and pugnacious and has its own moments of insight, like calling the James Gang "romantic terrorists" (169), or calling the UN a "debating society for third-world countries" (293), or the ironic phrasing in this sentence about Kent State: "Responding to an American public outraged by the four deaths at home and the 750,000-odd deaths abroad, Congress cut off funds" (329).
I'm sure that most people would learn a few things from this book. Recommended.
