Saw a post the other day: "I'm so glad I learned what a parallelogram is and NOT how to do my taxes in school."
Generally, people who say such things don't know what a parallelogram is OR how to do their taxes. They have been failed twice. They were presented with the signifiers of a liberal arts education but received none of the substance.
This isn't their fault and replacing alienating signifiers of a liberals arts education with signifiers "trades training" won't do what they think.
