According to Wikipedia a non-profit:

A nonprofit organization (NPO) is a legal entity organized and operated for a collective, public or social benefit... ... A nonprofit is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties.

Which to me just sounds like a business for profit just with extra steps.

Since non-profit organizations provide a social benefit and literally their name says non-profit then workers shouldn't be paid more than they need or rather, shouldn't be paid based on their skillset or shouldn't be expected to pay high like that. Seems counter-intuitive that an organization that wants to provide a benefit somehow still has to make the same money as a for profit.
