@TizerorFizz -
I'm allowed to think the degree was not really worth it. It was my experience.
Why does that offend you? Are you the admissions office for MFL at Oxford or something?
There were multiple things about the learning experience that left something to be desired. I got an ESOL qualification after my degree overseas and the teaching was a lot better than anything I experienced at Oxford.
I have learned a lot more through working life than I did from my degree. I only had a few hours of contact time per week, and 6 months of term time. It was quite an isolated way to learn, and I often felt the dons were disengaged and simply wanted to get back to their research.
Duolingo is only suitable for the first 6 months of language learning, as I've already explained. It isn't a substitute for a degree. Living overseas, reading widely in different areas (history, literature, linguistics), consuming media, having lessons, and having a partner and friends in another language is a substitute for a degree. I am an avid reader and learner, and I was before my degree.
I didn't start making the big money until my 30s.
