Credit Card Spokesperson: "It is to the benefit of all credit customers that we increase the interest rates of those cardholders who present a high risk of defaulting on their obligations. A way to offset the costs of these customers' defaults is to increase the interest rates of all customers, including those who are at almost no risk of defaulting on their lines of credit."
Which of the following, if true, most strongly indicates that the logic of the credit card spokesperson is flawed?The spokesperson says raising rates on high-risk customers benefits everyone, because defaults create costs that must be offset. But the flaw is that the proposed solution may actually make the default problem
worse rather than better. If higher rates make risky customers even more likely to default, then the policy undercuts itself.
(A) Credit card companies could offset the costs of defaults by raising the fees they charge to merchants who accept credit cards.
This gives another possible way to offset costs, but it does not show that the spokesperson’s logic is flawed. The proposed policy could still work even if alternatives exist.
(B) Increasing the interest rates on high-risk cardholders is more likely to result in these cardholders defaulting.
This is the best answer.
It directly attacks the logic of the argument. If raising rates on high-risk customers makes them even more likely to default, then the policy may increase the very costs it is supposed to offset.
(C) Many credit card customers pay their bills in full each month, avoiding interest charges.
This is not the key flaw. It shows some customers would not be affected much by higher rates, but it does not undermine the logic of the spokesperson’s proposal.
(D) Increasing interest rates would not result in a higher monthly payment for high-risk cardholders.
This weakens the practical effect of the policy a bit, but it does not expose the main logical problem as strongly as B does.
(E) Credit card companies have historically offered cards to high-risk customers at higher interest rates than those given to low-risk customers.
This does not show any flaw. If anything, it suggests such differential pricing is already common.
Answer: (B)
