"The Council of Graduate Schools produced a study on the PhD completion and attrition. The study looked at 49,000 students attending 30 institutions in 54 disciplines comprising 330 programs. Astonishingly, the completion rate ten years after students begin their doctoral program remains low at 56.6%."

even when accounting for external factors that could lower that number, it is pretty low.

but you say

"Many PhD students are dumb as rocks. After you get in it's very hard not to graduate."

your school is ranked higher in what? nonsense?

what you're saying doesn't add up. so i am just going to go with the reasonable path of ignoring you.
