This is a problem in every social/political organization which is not ruled by interested minorities. So, co-operatives, voluntary social activity clubs, democratic NGOs/associations, professional societies, etc. Democratic states suffer from this also, although it's arguable whether they're not ruled by interested minorities to begin with. In fact, the unfortunate public-opinion manipulations we see in national and international politics are also often present in smaller, local organizations, albeit in less-well-funded and less-spectacular form.

I'm always reminded of the Anarchist Peasants:
