I’m not disputing the assertion, but just pointing out Reason’s list is a bit misleading in the engineering department. All fifty states license engineers, but some specify on the license which discipline was tested. Either way, electrical engineers all take the same electrical engineering exam, whether the state will license them simply as “Professional Engineer” (like North and South Carolina) or designate which field is licensed (like Louisiana). To say that North Carolina registers “Engineers, All Other” but not “Civil Engineers” misrepresents the situation.
Also, for what it’s worth, all the states I’m familiar with only require licensure if the engineer is in private practice or government projects. An employee of a manufacturer, say a chemical engineer working for a paper company, isn’t required to be a P.E. — the company is assumed to take the risk, not the public at large.
