Some economists argue that markets, like languages, are complex systems that evolve best without central control. Languages, after all, develop rich grammar and vocabulary through countless individual choices; therefore, we should leave markets entirely unregulated if we want optimal economic outcomes. Attempts at regulation, they claim, are akin to imposing grammar rules that stifle natural fluency and creativity. Thus, the analogy purportedly shows that planning only hinders efficient order.
Which one of the following, if true, most seriously weakens the argument?
- Language academies often publish dictionaries that codify patterns that already exist in everyday use.
- In many historical cases, unregulated markets produced monopolies and systemic failures that reduced consumer choice, whereas language evolution has no mechanism allowing a single actor to restrict everyone's options. (correct answer)
- Entrepreneurs frequently use metaphors from language when describing market behavior.
- Regulations frequently impose compliance costs that can constrain innovation.
- People can communicate effectively across dialects without any central planner.
Explanation: The argument relies on an analogy between markets and languages; B highlights a crucial disanalogy by noting harms unique to unregulated markets that lack a language parallel. The other options either support the analogy or are irrelevant.
