Nonprofit organizations will always exist.
Individuals will always find reasons to organize themselves, permanently or temporarily, to do things for no reason other than they think it’s the right thing to do. There will always be market failures that mean people won’t pay for benefits they can get for free or that people won’t pay for benefits that go to somebody else. There will always be services and needs that government can’t or won’t provide.
The volunteer-led organizations in any culture tell you so much about what people truly value, seek, and need.
