Licensure... is it worth it?

I read about how licensure offers no real benefits and only restricts the number of opticians available in certain jurisdictions. I cannot agree.
Licensure, whether in Canada or USA, requires the formal learning of certain core competencies and provides for the blend of both theory and practical training, so that qualified ‘licensed’ opticians can usually troubleshoot almost any dispensing problem. And even with formal opticianry training, many Opticians (and even OD’s and OMD’s) need to request help from fellow OptiBoarders for a new or complex optical issue.
It is always a false economy to hire ‘off-the-street’, and then provide only rudimentary opticianry training to save on wage costs. Yet many doctors and opticals continue to post employment ads that say “No experience necessary”. The costly and embarrassing re-dos that result from unqualified staff cannot end up being truly cost effective. The newly-trained employee will eventually want a better wage, but will still lack the necessary optical background to avoid future dispensing errors. Sure, such errors can always be blamed ‘on the lab’, but the operation still loses some credibility with the public. And with the huge wholesale costs of some specialty lenses, even a 50% redo lab credit is still very costly.
Some untrained employees complete the basic ABO and then consider themselves qualified ‘opticians’, yet almost all could not resolve standard dispensing issues involving aniseikonia or vertical prismatic imbalance. Only mandatory formal opticianry training for all optical dispensers can resolve this broken business model.
