I think you are confusing organizations and companies. Yes, under capitalism, companies only exist to reek in profits, but from a non-profit organization you'd expect something else...
NGOs and government organisations follow the same pattern. They all expand, hire, and the people within each org all have a vested interest in the organization expanding and keeping them all employed, given raises, etc...
Substantial Organizations - whether capitalist, non-profit, or other - give a great deal of power to their leaders, and jobs to their workers. Those folks - most especially the former - may give lip service to the org's supposed mission...but their for-sure #1 priority is looking out for their own interests.
