Purpose: The prioritization of multilingual and multicultural education (MME) must spread beyond educators and researchers, who have long known the benefits, to the politicians and policymakers and to the general public. This paper aims to propose that the MME field needs a good economist who can explain MME benefits in terms of the language of economy, clarifying that economic advantages extend beyond diverse individuals, including those who may be ideologically opposed, via increased economic output to potentially benefit all. Design/methodology/approach: Using a conceptual framework, connections are demonstrated between MME and increased cultural and linguistic sensitivity as well as between the effects of increased sensitivity on the potential for economic benefits. These connections can be logically extended to consider the effects of MME on economic output. Findings: Research indicates that MME can increase cultural and linguistic sensitivity and that increased sensitivity to cultural and linguistic diversity can affect economic output. A logical bridge between the two fields of research is illustrated. Originality/value: This paper uses a practical approach to support the flourishing of MME. If MME is, ultimately, to result in benefits that all can appreciate, it is imperative to get groups with various purposes on board. Then, maybe we can look forward to the effective and pervasive implementation of MME. The challenge remains that this message has not been reaching the general public, and a good economist's communication could be the key.
