Sociologist: A contention of many of my colleagues—that the large difference between the wages of the highest- and lowest-paid workers will inevitably become a source of social friction—is unfounded. Indeed, the high differential should have an opposite effect, for it means that companies will be able to hire freely in response to changing conditions. Social friction arises not from large wage differences, but from wage levels that are static or slow changing.
Which one of the following is an assumption required by the sociologist’s argument?
(A) When companies can hire freely in response to changing conditions, wage levels do not tend to be static or slow changing.
(B) People who expect their wages to rise react differently than do others to obvious disparities in income.
(C) A lack of financial caution causes companies to expand their operations.
(D) A company’s ability to respond swiftly to changing conditions always benefits its workers.
(E) Even relatively well-paid workers may become dissatisfied with their jobs if their wages never change.
EXPLANATION FROM POWER SCORE
This stimulus starts as many LSAT questions do—with a prevailing view to be disputed. In this case, the prevailing view is that the difference in wages between highest and lowest will eventually become a source of social conflict. The sociologist disputes this claim, concluding that the difference will have an opposite effect, because companies will be able to hire freely. He claims that social friction does not arise from high wage differences, but rather from static or slowly changing wages.
Premise: Social friction arises from static or slow changing wages.
Conclusion: The ability to hire freely will reduce social friction. In order for this conclusion to be properly drawn, the author must believe that the ability to hire freely must somehow make static or slow changing wages less likely.
The question stem asks for the assumption required by the sociologist’s argument; this is a Supporter Assumption question, and the correct answer choice should provide some link between the ability to hire freely and the absence of static or slow changing wages—for the author’s conclusion to hold, it must be the case that the ability to hire freely must allow companies to avoid static or slow changing wages.
Answer choice (A): This is the correct answer choice, as it provides the link between the rogue elements referenced above: When companies can hire freely, wage levels tend not to be static or slow changing:
Premise: Social friction arises from static or slow changing wages.
Assumption: There tend not to be slow or static changes to wages when companies are able to hire freely.
Conclusion: The ability to hire freely will reduce social friction.
Once we make this Supporter Assumption explicit, we can see that the argument flows logically.
Answer choice (B): The conclusion in the stimulus does not concern
reactions to wage change expectations, but rather the relationship between static or slowly changing wages, social friction, and companies’ ability to hire freely. Since the sociologist’s conclusion makes no distinction regarding how people react to disparities in income, and this choice makes no reference to the unlinked elements of the author’s argument, this answer choice is incorrect.
Answer choice (C): Expansion of business operations is completely irrelevant to the sociologist’s conclusion, and this answer does not tie together the prephrased elements listed above, so this answer choice is incorrect.
Answer choice (D): It may be the case that a company’s ability to respond swiftly to change always benefits workers, but since this choice does not provide the necessary link between the rogue elements referenced above, this is not the Supporter Assumption we are seeking.
Answer choice (E): If well-paid workers become dissatisfied if their wages never change, this may help to support or explain the author’s assertion that static wages lead to social friction, but this answer choice does not link the premise about static wages causing social friction with the conclusion that when companies can hire freely, social friction is reduced.
