It could be said that liberal arts is the study of what makes people human - not tool-using mammals or faceless economic units, but thinking, feeling, creative beings.
As such, the focus of liberal arts is not closely associated with making money. It's obvious once you think about it, though, that the natural human desire for beauty, truth, and order also plays a major role in all business activities, from marketing to product design.
This means that liberal arts graduates often fulfill crucial roles in the workplace, especially if part of their course of study included more practical subjects like communication or graphic design. They also tend to excel at "soft" skills not widely taught as part of engineering or finance degrees: critical thinking, collaboration, and creativity to name a few.
Liberal arts students tend to have a relatively broad view of the world and their place in it, welcome new ideas, and communicate effectively. Most liberal arts programs in Europe can be customized to suit the student's individual interests and can include courses from the sciences, mathematics, and engineering faculties.
