Things have changed, but there are still some good outlooks for math/computing students. An MS in applied mathematics, statistics, software engineering, or machine learning will open a lot of doors, even these days, in industry/ business/ biotech/ government (particularly with a background in a relevant field like biology or business). Academia is getting worse in those fields, though, and some of the academic friends of mine have left academia for industry. No reason to slave under a low salary and long hours of a faint chance of tenure when industry will pay top dollar and let you work from home half your week... Even without a PhD or even an MS, a good amount of BS's in applied math are finding solid employment (actuary, statistician, business analyst, data scientist, database engineer).
Biology, social sciences, and humanities, however... To be fair, a lot of the more recent PhDs I know have found something, just not in academia (private high school, community college lecturer, pharm/biotech).
