Non-profits could be For-profits

Much of the best work going on in the world is being done by nonprofit companies.

My question is, can people make money doing that work?

In general, employees of nonprofit companies get paid. The only difference is that the people supplying the money don't expect their money back, or a return on investment.

Why not? In some cases, the work itself is donated to poor people. But I am wondering if this is the best way to help people. Maybe charging them money would cause us to address the reasons behind why they "need help" in the first place.

I used to think that working without profit was somehow more noble than working for money. Now I think money is a good thing and trade is healthy.
