After this rant, here some practical tips though.
Depending on their background, show them something from

• Andreas Antonopoulos, if they have some technical abilities. Videos mostly, maybe his book on Bitcoin.
• Lynn Alden, if they want to believe they can predict the future by analyzing macrotrends. Her book, or her recent video on why money is broken,.
• Saifedean, if they're brain dead idiots who want to join a cult. Any of his books, it's just recycling the same stuff over and over again.
• Alex Gladstein, if they want to fight injustice in the world. Check your financial privilege book.

I'm being a bit tongue-in-cheek here with some of my descriptions, but you get my point, I hope.
