Many economists claim that financial rewards provide the strongest incentive for people to choose one job over another. But in many surveys, most people do not name high salary as the most desirable feature of a job. This shows that these economists overestimate the degree to which people are motivated by money in their job choices. Which one of the following, if true, most weakens the argument? ['In many surveys, people say that they would prefer a high-wage job to an otherwise identical job with lower wages.', 'Jobs that pay the same salary often vary considerably in their other financial benefits.', 'Even high wages do not enable people to obtain all the goods they desire.', 'Some people are not aware that jobs with high salaries typically leave very little time for recreation.']
