Who cares, if a graduate is using their degree? Is an 18 or 20 year old supposed to understand what they are passionate about in life - and pursue that immediately after high school?
What a joke. Maybe someone else could be so lucky.
Whoever paid for that unused education probably cares, especially when the graduate ends up unemployed or underemployed.
For most people, most of the time, work isn't about "passion" but rather it provides the means through which to support themselves financially.
In addition, working class "passionate" people are vulnerable to exploitation, as e.g. seen in the videogame industry, the media industry, etc. "Passion" is only a benefit to those too wealthy to fail.
Your case would not count as underemployment (of which examples are office support, retail sales, food service).
But like others have pointed out, I don't think there's anything wrong with getting one master's degree, and then ending up working in some other field where a degree is beneficial. But people with master's degree working minimum wage jobs that don't require education and they don't like, now that is depressing.
I honestly don't care if I am using the degree, but I also didn't pay what the kids are paying these days.
