How does Hawaii's economy primarily benefit from tourism?

Hawaii's economy primarily benefits from tourism because it serves as a significant driver of revenue generation, job creation, and support for local businesses. Tourism accounts for a large portion of Hawaii's GDP, and visitors contribute to the economy by spending on accommodations, food, activities, and transportation. This influx of money not only boosts revenues for the state but also sustains a multitude of jobs in sectors such as hospitality, retail, and services. Additionally, local businesses thrive from the demand created by tourists, prompting increased economic activity and growth.

The other options do not capture the primary role of tourism in Hawaii's economy. While investment in real estate and agricultural exports may have their importance, they do not directly generate the same level of immediate economic activity and employment as the tourism sector does. Higher taxes collected from citizens are also not a direct benefit and could limit disposable income, contrasting with the positive impact that tourist spending has on economic health.
