the greatest spend thrifts in the society". 12 .
Not only did Adam smith talked about the Invisible Hand, but he also talked about the Division of Labor. In his essay "The Division of Labor in The Economy, The Polity, and Society" Kenneth J. Arrow says that Adam Smith made the division and the subdivision of labor because it helps in the improvement and the expansion of output, and he proofed this by giving three reasons. 13 The first reason, that Smith gave, is that when you perform a simple or a small task for a long time, this improves your ability in doing this task. 14 Second, when shifting from one job to another, this makes workers waste time, but on the other hand the Division of Labor accumulates and saves time. 15 Smith's final reason that is mention in the essay of Arrow's is that when a worker is concentrating on a specific task, this enables him to advance the performance of the machine he is using. 16 Arrow's main interpretation about Smith's Division of Labor is neutral, which means that it holds positive and negative characteristics. He says that the Division of Labor helps in the growth of the economy, and it helps in reducing the set-up cost. 17 But on the other hand he says that this Division of Labor has some negative aspects. First, " it prevents individuals from possessing tender sentiments and good judgments about public life or even about their own" 18 In other words, it affects the workers negatively by letting them have wrong opinions about the normal life whether it was their life or others life. Second, it encourages on the elimination of education because you do not need to have a wide range of experience and all what you need is how to do your small task, and this for sure kills the talents in the workers. 19 In addition, the final negative aspect that the Division of Labor gives according to Arrow's opinion, although it gives more essence to cooperation, but it also increases the cost of that essence, and gives space to feuds to appear and take place.
