I often see mass media quoting some professors, and I always wonder how well-paid they are. “Professor” in the American context means “anyone teachoing above high school levels” including leturers. Most of the employers are colleges including community colleges. However, Singapore’s JC and polytechnic are probably comparable to U.S. high schools.

https://www.forbes.com/sites/andrewdepietro/2023/08/24/highest-paying-college-professor-jobs-of-2023/ is fairly credible. It shows 15 departments where teachers earn highest salary. For each department, it shows average (not median) and 75th percentile.

Humanities lecturers tend to make less than their counterparts in the sciences, law, and other specialized fields.
