In the inter-war period, officers led a "country club existence". They had a high social standing, equivalent to that of an upper-middle-class professional. They normally worked a 30-hour week, which gave them plenty of time to spend with their families, and for sports. They and their families had access to free medical and dental care. They had free life insurance, and an adequate salary, which could be stretched because Army commissaries and post exchanges sold many everyday goods tax-free. They invariably lived on-base in good housing, and in tight-knit and supportive communities. When posted overseas, they took their families with them. A secure and steady job was highly prized during the Great Depression years from 1929 to 1939, and resignations were rare.
