Professional labourers? Why not? It's certainly possible. The *good Judges' criteria which creates the most margin (from what I exhume) is "set standards of practice and enforce them".

Why would one perform something they aren't good at?[eg] It tends to make 'professional' more of an attitude (or lack of) than anything... not that anyone could be fooled by a 'pretender'.

So is it the money + diplomas + 'tude and/or any combination of one or two of the above? This seems to defy all mathematical proofs available toward a logical definition, and the members of this board (as professional wordsmiths)can't stand for that!
