Liberal arts schools aim to help people become well-rounded. Well-rounded people tend to be healthier and more social. Single-tracked people who are focused on becoming multi-millionaires may not be too happy in liberal arts schools.
Instead of being furious and bitter, try to find some value in the class. You WILL hate it if you tell yourself even before you start that you will. Sometimes it is the journey between “point A to point B” that is more meaningful than the destination. You will enjoy life better if you can learn to appreciate the journeys in life.
