Examining data without analyzing is just not too bright!
Middle class families (Read: one generation from a "hillbilly" grandmother), my family includes: One niece with a Phd, one with an M.A., another with a B.S. in Biology, another with a B.A. in Art (and is a recognized artist), a sister-in-law with a B.S. in Nursing, a BIL with an MA in counseling, another SIL with a MA in teaching, BIL with degree in accounting, niece with a Master's in History and 3 nephews with Master's in computers and/or Electrical Engineering, a wife with a BA in English and an MBA, and I have a BS in Biology and an MS in Biology. Only my FIL had a degree.
Granted, I have only used Calculus once since college and Advanced Algebra (quadratics) a couple of times. But use of fractions, simple algebra, etc. is pretty much needed. And, regardless of what some say, the ability to speak well marks an educated man!
While in grad school, I took the California Basic Educational Skills Test (CBEST) in order to substitute teach. At that time, it was a 6-hour test and you could take it 3 times in order to pass. It had 3 parts: English, Math and Writing. If you passed one section, you still had 6 hours on your second try but didn't have to redo the part you had passed (6 hour for 2 sections). There was a girl who was already teaching on an emergency cert who was on her third try and still had not passed the writing part (a sort of "What I Did Last Summer" essay). The English was basic (What is the verb in this sentence?) and the math no longer included even simple algebra; just 8th grade math!
