Disrespectful Pros has been the norm in my Scouting career. That has involved many years in 6 councils, and i cannot tell you the number of pros. Good ones leave because they also get abused and disrespected.
As councils merge this behavior becomes less and less acceptable due to the talent pool being forced to optimize as the promotion path steepens.
A bad professional in a pool of 10 doesn't look so bad due to limited peer comparison opportunities. Toss that professional into a pool of 30 peers and average or mediocre will reveal as poor and incapable.
In my neck of the woods, the folks who know what to do at the district and council levels have been run off pros. Reason is they see the mistakes the council is making, and when they bring it to the pro's attention, the get ignored, yelled at, or cursed out. They either get removed by the pro, or quit out of frustration.
I think the CST model is failing because the CST volunteers are overwhelmed at how poorly qualified the council and district volunteers are. Imagine the routine things that filter up because so many buddies of a buddy are chairing district committees, and how many council committees are chaires by people that have great checkbooks but ZERO domain knowledge.
The problem with on scouting is that it's a qausi official source and not a real official source.
