@J. K. Galbraith:

I think your point is fair. The scale of these enterprises is massive and requires expertise in order to work. Nonetheless, many people won't accept that, and I have seen that affect donations. 

I have specifically turned down a position in this sector - a dream job, really - because I didn't want to be branded as someone "earning six figures from a charity". The irony is that my present job in the private sector earns me way more than I would have in that role (or when I worked in the public sector), while requiring that I do LESS work. These experiences - and experiences shared from friends with both public and private sector experience - are why I always roll my eyes when people talk about the exorbitant wages in the public sector. Speaking diplomatically, both sectors have their issues.
