The conclusion you can draw is that tertiary sector specializations would earn the highest wages.
This is because the tertiary sector (which includes services such as finance, healthcare, education, and technology) typically offers higher-value jobs compared to the primary sector (which focuses on resource extraction and agriculture) and the secondary sector (which involves manufacturing). The quaternary sector, while also specializing in high-skill services, is often considered a subset of the tertiary sector. Thus, while it could also lead to high wages, overall, tertiary sector jobs tend to provide the highest remuneration levels in the economy.
