I chose to listen to the WTS when I was young and did not go to college right out of school. I was fairly lucky to get a position with a company that gave me chance. I took advantage of that opportunity and was able to establish a career. I ended up going to school part time in my 30s (this was after obtaining a few professional designations that were enough to allow me to continue moving up in my career) and finished up close to 40. Having that degree was critical in allowing me to continue to progress in my career. So, in that sense, it was worth it. I learned some valuable things and was happy to have gone through the process.
I've decided against a masters because in running a cost benefit analysis, it's not worth it. I'm better off investing in my children's educational pursuits.
Although it was almost 10 years ago, I don't recall any professors expressing any real leanings politically. I took a ton of business courses and the only political commentary was relating to taxes and governmental regulations. In most of those cases, my professors were more conservative than liberal. I could imagine that certain degree programs would lend themselves to a more liberal commentary. But, I was there strictly to move my career along and didn't take any of those types of courses. To me, if the course didn't directly tie to my degree or give me a skill set necessary for work, I didn't take it. I have other interests but don't think I need to pay the cost of a college course to learn more about those.
To each his own but I'm happy I obtained a degree and am encouraging my kids to do likewise if they are interested in careers in which one is needed. Or if they have no idea what they want to do, a degree can give them the foundation they need if they apply themselves.
