Opinions wanted please - Where are all the arborists?

I think the answer to the question asked is, “They are all working”.

There has never been so many Arborists.
They are either directly employed, provide regular subby roles to several companies or have set up on their own. 
There are no decent climbers/groundies that aren’t working in some form, they certainly aren’t registering on recruitment sites for work.

So the question should really be, “Where are all the unemployed Arborists?” as those are the people you are actually looking for.
