What is this obsession with plumbers lately? I respect them and their profession as one of the many professions and careers that humans can pursue, but the push for plumbing is now a cliche, and it is used as codeword for "higher education is bad." Do you not understand that this usage also disrespects plumbers, insinuating that they're all dumb oafs only good for unclogging toilets?
