Teaching is an honorable, but difficult, job to do. Economics instructors working in higher education must rapidly and thoroughly communicate complex concepts and theories within tight semester time frames, effectively enough that most students will learn the concepts and pass the course.

One of the key features of the global economy is that it tends to grow over time. In fact, that growth has become something of an expectation in the modern capitalist system, where the success of corporations is often judged by their growth, even over relatively short time horizons.

If you're planning to study economics at a Master's level, then you may have the opportunity to pursue a concentration, sometimes also referred to as a major. While rarer, some PhD programs may also offer concentrations, though many are already specialized degrees (or require you to have your own research agenda).
