Because different people have different motivations. People who are technically minded with a good grasp of logic and a desire to make and break things and who want a job study CS and get CS jobs (or just do CS and get CS jobs). Those same people, with slightly better math and no inkling of the job market study physics. Some of them stay in physics - and some, like me, move into IT then security, and just keep moving, having a great life all the way through. Those same people, with even better math and less make/break study math and some stay there and some become actuaries (what they intended all along) and some go into medicine (because math is one of the easiest science degrees to get, if you're good at math, no labs, so it's a pretty good pre-med). Same group, less math, more make/break: Chemists. And so and so on and so on. I took physics. Because I loved it and because it was super tough. Job prospects? Whatever. Fell out of love, did a little philosophy and some CS, translated that into a 25 year IT Security career, last dozen as a consultant, work when I want, do some acting, have a psychology exam next week.... tl;dr? The author had it right in the first bullet: These people study what they love and the rest be damned. They are not thinking jobs and as long as analysts have only that material mindset they will never get it. They are thinking love. Some people survive on that love, some thrive on it, some crash into despair, and some of them move on. That's life.
