From Tom Bethell's review of it here:
Ortega y Gasset’s Revolt of the Masses was published in 1930, but don’t be misled—its author was hostile to the masses. They had attained “complete social power,” and he resented that. The masses “neither should nor can direct their own personal existence.”
Fred Siegel’s Revolt Against the Masses (Encounter Books) takes issue with Ortega and can be seen as a belated corrective. A bracing, well-written reinterpretation of liberalism, Siegel’s new book identifies a political trend that has been in place for decades, yet is rarely noticed or mentioned.
It is subtitled “How Liberalism Has Undermined the Middle Class.” Siegel calls them gentry liberals—our equivalent of old-fashioned Tories and every bit as class-conscious. In the 1960s they took up “the priestly task of de-democratizing America in the name of administering newly developed rights.”
His message, says Michael Barone, co-author The Almanac of American Politics, is that “the roots of American liberalism are not compassion but snobbery.”
