>>1001690531) "Business Management" have always had by far the most job availabilities, but also by far the most graduates. So I imagine that the actual job availability-to-graduate rate is much smaller than many of the other fields on that list.
2) "Business management" is a very generic degree field which doesn't teach many hard skills, it just prepares you for generic corporate work/being manager at a Denny's. It can't really be compared to the other fields since, once your career is established, you are moreso defined with your history with the company than your skills.
3) these jobs are way more highly sensitive to having good connections/going to a good school than other fields. A fortune 100 company would hire a Dev/IT guy/accountant from any podunk state school, meanwhile they would autofilter any business grad from the same schools.
4) almost all of those business jobs, except for the restaurant/store management positions, are MBA positions that require graduate work.
