You are correct. The reason is simple. In the past teachers / educators went into the line of work because it was a calling. They had passion for teaching. "Adding" something wasn't a chore. They did what it took to teach. Many teachers used to spend significant time outside of the classroom time helping students. Why? Because they were very clear regarding their role in education. Today, in contrast, most 'teachers' enter the profession for the compensation and in order to get the summers off. For some it is quite obvious that teaching is a secondary exercise.
