I think the data analysis in this article is garbage. It draws conclusions first and then selectively looks at the data to support their argument.
A core principle all students who major in Finance learn: "the time value of money"
-A dollar earned today is more valuable than a dollar earned tomorrow, because you can invest the dollar earned today so it earns money for you tomorrow.
A core principle all students who major in Economics learn: "opportunity cost"
-In addition to the financial cost you pay to do something, there is also a hidden cost you're paying by NOT doing something else. (For example, the financial cost of grad school is tuition, the opportunity cost is the money you could've made if you had held a full-time job instead of going to grad school)
"But while focusing on more practical majors — such as business — may seem like the best route in the short term, majoring in the humanities may be more beneficial in the long term. In the first years after graduation, social sciences and humanities majors earn less than people who have pre-professional degrees, but at peak earning ages, liberal arts majors surpass people in pre-professional degrees, in part because they are more likely to have graduate degrees."
Reading this quote, the author seems to be looking at the maximum-average earnings on a year-to-year basis. For a meaningful analysis on this subject, I'd like to see the author look at lifetime earnings. Year 1+Year 2+Year 3+Year 4... And when you factor in the additional expense incurred to attend graduate school and then factor in 4 years of lost salary?

My undergraduate degree was in Finance. If I went back and got a MBA today, I'd make more money on completion. The salary increase would not justify the lost earnings. If my employer offered to pay for it (executive MBA in addition to work) I'd be more likely to consider it but I'd gain more value from a masters in science for something like Computer Programming, Statistics or Data Analytics.
Brad Hershbein, an economist at the W.E. Upjohn Institute for Employment Research, said students who major in business are less likely to want to go to graduate school “not so much because they can’t get in [but] because they are more likely to end up in a job where it is not necessary, which is probably a lot of reasons why people study it in the first place.”
