It sounds very similar to when I was in seminary. They literally had classes on how to manipulate your audience. How to “use vocal patterns and body language to make yourself appear more sincere.”

People severely underestimate how many shitty people there are in this world (and even those who appear trustworthy) that would eat your firstborn to increase their net worth if it wasn’t illegal.

I think it’s more that people who tend to be billionaires tend to also be kinda scummy people.
