I think that reading the blogs that appeal to you, watching the youtube videos, and my most important tip, reading comments and forums are 100x more valuable than a big name class would be. When I went to CMTO/CMC, my most valuable FI learning experiences came from talking in between sessions to people closer or further to FI than I am. There's also a questionable joke that for the big FI bloggers, starting a successful FI blog unretired them or sustains them in ER, or is a key strategy piece. I don't think it's always true, but I think that a lot of the non-blogging LEAN-FIRE people I met were more relatable to me, and could give specific understanding and advice for my situation.
I'm quite sure that some people WOULD pay for your online masterclass. But I'm not sure if you could produce it at a cost that would be fair to someone still in a consumerist mindset and looking for help. If you do, I suggest a disclaimer like Ramit Sethi's where he provides 90% of his content free, and won't sell his courses to people in debt. In my experience a Masterclass online seems to be in the high hundreds to mid thousands. I would be sick recommending that to a friend, even if I followed it and was happy.
If you're looking for an entry-level product,
@monstermonster created this:
https://ohmydollar.backerkit.com/hosted_preorders. With prices ranging from $5 for an ebook to $39/$89 I bought it to share with some of my hair on fire friends, and have recommended it (and other great resources like Gail Vaz-Oxlade's books) to my higher income hair on fire friends. I also tend to send them links to blog articles by MMM about how much you need to retire, inspirational stories about people buying houses or becoming nomads or taking extreme measures to pay off debt. I usually include a disclaimer about finding x part of the article nuts, but if you look at the general principle, maybe we CAN do this.
