I disagree a little with their cost of living calculations - they're off in both directions for areas I know reasonably well. Most Ph.D. students can live for something under the MIT living wage calculations if they choose -- transportation costs are overstated for most places (e.g., CMU students get a free regional bus pass; MIT students get subsidized transit passes, etc.). Often the medical costs are subsidized as well -- we cover the full cost of (individual) health insurance for Ph.D. students.
You're not going to be banking much, but in CS, it's OK at many institutions, particularly when you factor in summer internship income.
As maligned as the poverty lines are—and they do have plenty of shortcomings—they are still a far closer approximation of "the true cost of living in a modern economy" than this drivel.
†No, really, go compare the "living wage" figures (https://livingwage.mit.edu/) with AMI stats (https://ami-lookup-tool.fanniemae.com/).
Which is generally above poverty levels right
Then at graduation I was offered a well paid job in the industry. Decided to pursue it as opposed to spending 5-6 more years in academia looking for grants.
Would love to go back and get a PhD, but the economics just don't make sense for me. For now, it's a retirement plan.
