Final answer:
Cheating is on the rise due to higher levels of inequality, lack of punishment for cheating, and the glorification of wealth and status, but not because of declining wages, according to David Callahan's research.
Step-by-step explanation:
The question pertains to the reasons why cheating might be on the rise, based on the research of David Callahan. According to Callahan's findings, all of the following are reasons for the increase in cheating except declining wages. Higher levels of inequality, cheating going unpunished, and the glorification of wealth, status, and personal gratification have been cited as contributing factors. He suggests that rising inequality, especially, can create pressure that incentivizes unethical behavior, and when individuals observe others gaining from dishonest acts without repercussions, they may be more inclined to cheat themselves. Additionally, when society highly values success and achievement, this too can promote cheating.
