Most PhD students are pretty much done with classes after the first year or two. They get their PhDs through research (often writing their own grants) or the vital function of teaching. They are workers. It is disingenuous to view them as students. If PhD students were not able to make a living, very, very few people would ever be able to enter science.
Somehow my 6 years of PhD in physics begs to differ.
As I said in another comment, grad students are going to grad school and getting a big bump to their future earning potential, subsidized often by the state. I don't think it's an entitlement that they get to do that for free, much less claim a right to earn living wage level on top of that.
> Maybe you were doing a CS PhD or something
LOL
> PhDs in most fields are not a good good way to maximize earning potential, especially when taking into account lost potential wages and the time value of money.
Nobody made anyone get a PhD in a field that doesn't pay, and so that doesn't mean they're entitled to high pay.
It's not hard to google "starting pay for major x" before making a choice. Nobody should be surprised at what the pay is, especially for someone capable of getting a PhD.
(And it’s not true grad students ‘often’ write their own successful grants. The vast majority of STEM grad students are supported on stipends from their advisor’s research grants or do a TA-ship when desperate.)
