Perhaps, the upside of the Roman Catholic church is that it is so organized and centralized.
Good point -- they map out the need. I'm sure other denominations do that too, but maybe not in collaboration.
Some of these preacher are millionaires.
Some of them started from very humble beginnings, and intent to please God. But look at what monetization and good planning led toward!
The successful ones knew they could not do it on their own, and gathered others to support them in their ideas -- hired staff, formed boards, and eventually spun off into books and tapes. Then people ask for more books, tapes, and speaking engagements, and one feeds another. Publicity breeds fame.
A certain artist became famous by promoting himself well, and schmoozing. The other artists in that town grumbled and compared their careers to his -- they worked so hard, and continually struggled... while his name was thrown around the wealthy circles.
His name was thrown around because he implemented a strategy to throw it around. His work was not unusually better, he just chose a different approach. And the died-in-the-wool purists viewed his commercialization with disdain, and chose not to take his path to success.
It changed the nature of how art was seen.
People did not want to sell out, or pretend to like wealthy collectors, or produce what other people dictated they should produce. They wanted art to retain its power as a voice, a statement about truth in the world. They wanted their art to be appreciated for its statements, craftsmanship or aesthetics -- not for how much an investor could profit from resale.
Christianity can go through those same comparisons. There are people who glean success and profit from it, and those intent on keeping truth pure.
