Developer Hegemony is interesting. I don’t agree with Erik that you can classify the corporate/business world as simply as he does, for one I think the “idealist” part of his spectrum is probably two to three separate personas (idealists, chronically-anxious, grateful/approval hungry). I do value, greatly, the encouragement to strike out on business though.
Rich Dad Poor Dad has some ok mental-model ideas that are great if don’t come from a background/family that exposed you to “the business world”, most of the rest of it is repetitive drivel.
I think these are fair assessments. I don't treat either or as gospel, and I'm always quick to invoke "all models are wrong, but some are useful". However, they both have some interesting insights that have helped my personal journey.
Rich Dad Poor Dad (Kiyosaki) helped me see debt differently. I grew up with the mindset that all debt is bad, it's slavery, and it should be paid off... and that money is meant to be saved. I now realize that money is meant to be deployed. Also RDPD has helped push me along to realize that debt is a tool, and like all tools there are ways to use it that can be advantageous.
Some good reads, although they may at first make you a bit depressed: https://www.ribbonfarm.com/2009/10/07/the-gervais-principle-... and The Developer Hegemony.
Robert Kiyosaki, of Rich Dad Poor Dad fame, has some pretty solid fundamental advice - https://www.youtube.com/watch?v=ftBeTIDv8Vg
