I majored in History (emphasis on U.S., I’m in the U.S.) and German.
My first job out of college was teaching kindergarten. Forty years later I’m a full-time freelance writer, the majority of whose income comes from educational materials involving math. I have written a few history books for young adults and worked on some social studies programs, but on the whole I’ve done more ELA and much more math than anything history-related. As for German, well, it hasn’t played much of a role in my personal life, and none whatsoever in my professional existence.
Still, I don’t regret my majors at all. I enjoyed them both and as others have said they helped me learn to think flexibly and make connections.
Can you head over to the Financial Literacy thread and write a textbook on that?
Ha! 
I actually have written a couple of short YA primers on financial literacy topics, and I worked briefly on a personal finance curriculum for HS students at one point. And a long while back I wrote several chapters for a study guide for people who wanted to take the Series 7 exam. I had only the faintest glimmering of what this was all about before I started, and the learning curve was predictably steep, but I had a lot of help, the subject matter was more interesting than I expected, and the money was very good.
Now, as for the state of my personal financial literacy…well, them that can’t do, write study guides and primers. Or something like that.
I can only read the first paragraph. Do they acknowledge, anywhere, that a university degree is for more in life than post-graduation earnings?
No. It is, after all, The Economist.
I don’t necessarily regret my major, but my degree in Public Administration isn’t much use in my occupation as a carpenter/theatrical installer.
Even when I was working for government agencies, it wasn’t gong to be of much use since I had figured out that I had no desire to rise high enough for it to be useful.
But GI Bill paid for most of it and I guess it looked good on my resume.
