      By now you know that getting your money’s worth is not just a matter of luck. It is more often the      of buying skill. Nevertheless, even the smartest consumers are sometimes fooled into thinking they are getting their money’s worth when they are not. At one time or another, almost everyone experiences deception (欺骗）in the market place. The deception may not be    . But, whether or not, any kind of deception hurts consumers’ feelings as well as their pocket books. Some kinds of deception even endanger their health and safety as well.     , consumers need protection against the marketing of unsafe goods and false or misleading advertising. Fortunately, there are both public and      agencies working to meet the need. Government’s job in free enterprise system is to protect the public     _ . The public is composed entirely of consumers. When it comes to protecting consumers, therefore, government has the most influence. Because most consumer products are sold     , the major responsibility for consumer protection is      by federal government. That responsibility, however, is shared by many agencies. For example, the US Postal Service works to uncover and stop dishonest schemes operated by mail. The National Highway Safety Bureau is      with all aspects of automobile safety. Certain federal agencies, however, have consumer protection as one of their chief     . Most federal agencies are known by their initials. FDA stands for the Food and Drug Administration, which probably does more to protect consumers than any other agency. Its major concern is the safety, purity, and labeling of foods, drugs, and cosmetics. These are the products for which consumers spends a(n)    38% of their incomes.
