I have a sibling who has a math PhD and is an actuary. He said years ago that the colleges and universities will give away bachelors and masters degrees but they won't give away doctorates. I wonder about doctorates now with all the educated idiots running universities.
A doctorate used to be earned, but with so many doctorate programs today they are now given away. There is always lots of “make work” involved, but the rigor is no longer sincere. Do enough work and a student will always be awarded the Doctorate.
