“Secretary” was the sort of role most common for women in 1950, when career opportunities were -- ahem -- more limited, to say the least, and only a tiny fraction of women held college degrees. And it’s still the most popular role now, despite the facts that more women earn graduate degrees than men, and women are soaring across a vast number of industries.
