Where I come from (Germany), you're not allowed to do car paint jobs unless you're a certified varnisher. A lot of job titles have similar restrictions. These restrictions have more to do with the history of these professions than with their intrinsic qualities. In Europe a lot of them can be traced back to the late middle ages -- and in North America they can generally be traced back to Europe. I agree that these terms may have legal implications in some jurisdictions, but that's irrelevant to the discussion of whether they are accurate.
