I think a lot of people are missing the point. It's not that the economy is bad, it's that there's a mismatch. We have tons of graduates who just finished with a degree in X, but we need people for job with skills Y
It's unclear from the article, I'm just saying this is what the data shows. The economy is strong, and young people can find jobs, but the findings in the article suggest young people with degrees are having trouble getting jobs.
The example they give is a girl who has a degree in "health communications". Another, with a degree in "cognitive science", found a job in data science. A critical reader might describe these degrees as a "degree in fluff".
