Check out Stan Johnson of the "Prophecy Club" on YouTube and elsewhere. He's been riding various Evangelical trends since the nineties or even the eighties with promotional tie-ins to various enterprises, e.g. prepper food/technology, silver bullion, prophecy videos and conferences. I can't imagine he's making all that much these days and his hybrid physical/online seems small. He got the COVID-19 a couple of times and didn't bother to tell his still-meeting congregation about it until quite late.
He preys on the gullible ... but in some Black Swan event sort of way (e.g. extended regional power outage) his adherents may come out ahead for a short time.
Similar with Jim Bakker[1]. The guy went to prison for fraud and went straight back to televangelism when he got out and sells buckets of freeze-dried food to his parishioners to prepare for the end times.
