The argument posits that removing restrictions on advertising legal services will lead to more lawyers advertising and subsequently lower consumer legal costs, because advertising lawyers charge less. To weaken this, we should find a reason why lifting restrictions won’t significantly lower costs.
Consider the option: “Most lawyers who advertise specific services do not lower their fees for those services when they begin to advertise.” This statement suggests that lawyers who start advertising do not necessarily reduce their fees. If true, increased advertising does not equate to lower fees, contradicting the conclusion that lifting advertising restrictions will reduce legal costs. Consequently, this undermines the notion that advertising directly correlates with lower prices for consumers. Thus, this option most seriously weakens the argument.
