While I generally agree with you, You are over-generalizing. I know lots of young people with degrees in music, English, literature, geography, history, and other liberal arts degrees who all have good careers started. Businesses look for well rounded people who are capable of learning. I know a fair number of execs who started in those tracks, too. Your career choices are NOT limited to teaching other students those disciplines. Our oldest daughter got a masters degree in Human Geography and is an excellent and well-paid market analyst in the hospitality, tourism, and airline industries. Her ability to analyze data and write cogent reports all come from her liberal arts training. A lot depends on your drive, enthusiasm and ability to navigate career choices.
You are right, I was over-generalizing.
I am not saying ALL general studies are bad, but if you get a Liberal Arts degree in Underwater Native Basket Weaving, and rack up $150K in student loan debt in the process, you are an idiot and you wasted your time.
