The era of 1919-1929 in the United States, called the period of prosperity, is one of the most controversial in the history of this country. "The ultimate victory over poverty" and the nation as a "consumer society," the cult of profit and emancipation of morals with references to Freud, immigration as a threat to the state and racial theories, the Ku Klux Klan as a guardian of morality and Hollywood as a abode of vice, advertising as a public tyrant and tabloids as legislators of public opinion, "Prohibition" as a guarantee of the health of the nation and Al Capone as a symbol of prosperity, a war of gangster gangs and organized crime in the service of politicians... All this, which became for Americans the road of disappointment that led the country to the Great Depression in the early 1930s, so resembles our "perestroika," which started half a century later. And from this point of view, the book will certainly interest the widest reader.
