I don't disagree but the statement is also weird from the perspective of objective reality in 2023. My old PhD program's current 5 year graduation rate is way below 50%. I think it's like 10% if you don't count the MD/PhDs that are more likely to get pushed through quickly, but even including them it's not more than 25%. The 6 year graduation rate is barely hitting 50%! I don't know if it's field-dependent or if the Prof was just very out of touch, but graduation in 5 years is an anomaly at this point that actually suggests the person is more likely to have a planned industry (or medical school) exit. Weird to conclude the student is the problem en masse.
