The Chronicle of Higher Education has posted a recent article, "When Less Education Means More Money." With this article, they supply an interactive chart that the reader can manipulate. Education levels shown range from "less than high school" through to "professional," and also includes "some college," and "associate's degree."
Although the article does not go into specific careers associated with the level of education, it's still an interesting look that may help you figure out your own position on the scale, or determine where you might be on the scale, after you've completed different degrees.
