Diagram:
L - large wage difference; H - companies hire freely; C - changing wage levels; S - social friction
Premise: L → H
Premise: not-C → S
Contrapositive: (not-S → C)
Conclusion: L → not-S
I took the contrapositive of the second premise and connected it to the conclusion.
Premise: L → H
Conclusion: L → not-S → C
Assumption: H → C
Attaching the premise gave me a clearer look at where the gap lies. I’m not too sure if I’m within the lines of valid-logic in creating that contrapositive, but it seemed fitting!
Premises:
Responding to wage difference changes means that companies will hire freely.
Social friction comes not from a large wage difference, but from wage levels that don’t really change.
No social friction suggests that wage levels are changing
Conclusion:
The large wage difference will not become a source of social friction.
Task: Necessary Assumption
I have to identify the conclusion & its function, the support & its function, analyze the premises/conclusion relationship, and identify what the argument is taking for granted.
Analysis:
Companies being able to hire freely → wage levels won’t be static or slow changing
Answer Choices:
(A) This is the right answer. A relationship between these two ideas is the assumption the argument needs in order to survive.
(B) People who expect their wages to rise, and how they react to wage disparities isn’t fundamentally important to the argument.
(C) Financial caution isn’t brought up in / indicative of the argument. Side note: even though the idea of financial caution rubs me as irrelevant, I made sure by going over the text. There’s nothing of the information presented in the argument that entails financial caution.
(D) Regardless of a company’s swift response to changing conditions benefitting its workers, the argument can still get to its conclusion. A company’s ability to respond to changes is not the same as a company’s ability to hire freely. The argument isn’t taking for granted that benefiting workers leads to no social friction.
(E) Someone who is well-paid might not be among one of the highest paid. The well-paid workers class is not relevant to the argument.
