Because having a bachelors degree from a good (not necessarily elite) university should equip you to handle any number of jobs in general management or government.
If that's not happening, there could be a few different reasons:
1. Getting a BA isn't as rigorous as it used to be, and no longer means "This is an educated person. Besides their specialty, they should be smart and adaptable enough for most administrative-level purposes." Pseudo-professionalism has also closed the doors to some of these jobs, maybe as a way to get around civil service tests as a way for the educated to get government jobs without specific training.
2. The white collar, middle class job pool has been decimated, and not enough places need generally well-educated people.
This is still more or less the case in northern Europe. If you have a degree (in anything), the most likely outcome by far is that you lead a normal middle-class life. There is no big pool of unemployed Swedish BA/MA holders; rather, the unemployment problems are among people with no university degree.
