Agree, agree, agree! I worry that too many students try to backward manage their greek choice. I must be an investment banker. The house with the most investment bankers is Psi U/KKG (do not know the real data). I must join Psi U/KKG.
Most 18-19 year olds do not have a realistic grip on their career choice. They have perceptions based on their parents or friends engaged in a career, but they have sparse insights into the day to day grind of a particular career.
For most, a career is spent working with a group of people with a common goal (e.g., bankers, teachers, doctors). Most will spend 40-70 hours per week for 40-50 years with those people. If in college you did not like the people who end up populating those careers, it is unlikely you will find it changes after graduation. More importantly, where are the people with whom you would like to hang out for the next 40 years going?
Select the places where you spend time in college based on the people with whom you are excited to spend your time because of your common interests and passions. You are attending a liberal arts institution because you are open to learning and exploration, not as a vocational school to a specific job. Once you find a group of people that you really enjoy being with in college, whether or not it is greek, look at where those people are making careers and give that serious thought. You do not need to know that now. That is why you are attending college.
