73. Once during a U.S. presidential campaign, a lobbyist for a prominent national women’s
organization made the claim that women in the United States earn $0.60 for every $1.00 earned
by a man. A reporter, who was prepared for this statement, asked the lobbyist why wages paid to
the organization’s secretarial staff (all of whom were women) were significantly below the
national average if they were truly interested in raising the rates of compensation for women. If
you were the lobbyist, how would you have answered this question? Do you think your answer is
convincing? Explain.
