I just started reading Fantasyland: How America Went Haywire by Kurt Anderson. It's amazing so far!

Blurb:

"In this sweeping, eloquent history of America, Kurt Andersen shows that what’s happening in our country today—this post-factual, “fake news” moment we’re all living through—is not something new, but rather the ultimate expression of our national character. America was founded by wishful dreamers, magical thinkers, and true believers, by hucksters and their suckers. Fantasy is deeply embedded in our DNA."
