Oswald Spengler, 1933:
For the Age has itself become vulgar, and most people have no idea to what extent they are themselves tainted. The bad manners of all parliaments, the general tendency to connive at a rather shady business transaction if it promises to bring in money without work, jazz and Negro dances as the spiritual outlet in all circles of society, women painted like prostitutes, the efforts of writers to win popularity by ridiculing in their novels and plays the correctness of well-bred people, and the bad taste shown even by the nobility and old princely families in throwing off every kind of social restraint and time-honoured custom: all of these go to prove that it is now the vulgar mob that gives the tone.
