The Bridgespan Group, a consultancy for nonprofits, has identified a leadership deficit in the nonprofit sector. My take on the problem's cause? (I know, no one asked.) Likely there aren't leaders because lots of talented people in the sector who show potential are deemed threatening and/or uppity by petty leadership--and their efforts at success are sabotaged. I'm sorry if this sounds snarky, but I believe it could be easily documented. So that's why has to stop, IMHO. This applies to trade and professional associations every bit as much as the more fluffy cause-oriented groups.
