Sorry Don but I beg to differ. Quite a lot of organisations have gone under because of the B.Com, B.Bus, LLB, MBA, AICD people at their pointy end. I think you will find that there are a lot of professionally qualified people from other professions doing sterling work on a wide range of commercial and not for profit organisations around the world.
You might not be personally disparaging me but I think that the boards, large and small, work I have done over the last 40 odd years was of significant benefit to the organisations I have served. Some of my best friends are lawyers. One, in particular, one a board I currently serve on, is absolutely first rate mainly because he thinks outside the square and aims to understand the business and come up with novel solutions. No, he is not an aviation lawyer.
I must give a lot of credit to your achievements, twice, as Treasurer, and to Jim Tatlock. If either of you opened your mouths on treasury matter it was to speak sense. Having a B.Com doesn't always guarantee that outcome. Not having a B.Com doesn't indicate that the treasurer is a gibbering idiot.
Just because a board member represents the aspirations of his/her electorate to the board doesn't mean that they are bound to support the proposal, all things considered. The board members might advocate but must, at the end of the day, vote in support of the organisation, All of its members, and the rights of other stakeholders (including staff and those we have commercial and legal relations with). Having advocates on the board is not a bad thing.
Keep well
