>that things that are illegal but profitable happen, while things that are legal and unprofitable do not.

I'm not sure. I want to say there's volunteering, charities, clubs, religions etc. But those all need resources (time, energy, money) put into them to remain viable. I suppose if something is unprofitable it means the resources (money or not) are drained faster than they go in, and the entity dissolves.
