Well, he’s a capitalist then. Or should hussein collect the difference? No one says you have to buy it. There are a lot of writers I wouldn’t read. But others do, and even want to. Should they be denied by your literary tastes?
It has nothing to do with capitalism or literary tastes. I have no problem with someone writing a book and keeping all the cash. Heck, they can make a Scrooge McDuck pile and do backflips into it for all I care.
What I have a problem with is people claiming that the Holy Spirit “inspired” their writing, and then wanting to profit from it. If it came from God, it’s not your work, and you don’t get to charge people money for it. If you want to charge people, then fess up that you wrote it yourself and stop slandering the Holy Spirit.
