...you need recognized standards. If you are an electrician it is easier to approch this problem.

I completely agree that an electrician is going to easily learn and comply with the Code requirements of LV work whereas in my experience many if not most LV guys don't even know what the NEC or Code is and many don't even care.

During the early years of datacom standards were very much lower...

If you are talking about the standards for techs or workers, yes that's true but in many respects the thinking is still there today that anybody can install LV and it shouldn't cost much. So we have hacks who know nothing and customers who hire them and pay them nothing. Supply and demand.
