Totalitarianism in Mid-20th Century America.
Lewis has witnessed Hitler's history before it was fully played out and presents it as a drama on the stage of American politics (economic, social, etc.).
Accurate and, fortunately, not prophetic (as far as the American side is concerned, because Germany followed exactly this path), this book deals with the rise to power of the classic demagogue of the mid-20th century with indirect blows to democracy. What follows is what Europe experienced at its heart with Hitler's rise to power.
The parallels are clear and the harsh irony -bordering on sarcasm- of Lewis is enjoyable. The crowd that follows the populist demagogue who promises high incomes for all, the gradual, obvious (perhaps for readers who know what happened in Germany after 1934) but also simultaneously subtle transformation, the abandonment of any democratic pretense from a certain point on and the subsequent abandonment of logic itself.
As always, there are a few who resist (and there will always be those who resist), others with greater and others with lesser success, others are arrested and others lose their lives after mock trials, up to the tragic finale that deprives the work of its fifth star.
Overall excellent, especially when one considers exactly when it was written (first edition in 1935, if I remember correctly).
