"Instead of trying to get a PhD and a job in academia (which is very costly and due to "publish or perish" forces you to work on topics that are currently popular in academia), get a job that leaves you with a lot of free time" Part of the attraction of academia to me is that it is exactly the job that leaves you with lots of free time. A professor only has to be in a certain place at a certain time 3-12 hours per week (depending on teaching load), 30 weeks per year. After tenure, you can research whatever you want, especially if you aren't in a lab-science field that leaves you dependent on grants. Even before tenure I can work on neglected problems, so long as they aren't neglected due to their low prestige.
