Said in a 1942 speech by Robert Menzies, referring to the middle class, defined as lying between "the rich and powerful: those who control great funds and enterprises, and are as a rule able to protect themselves" and "the mass of unskilled people, almost invariably well-organised, and with their wages and conditions safeguarded by popular law"."
