Posting a salary range is hardly burdensome. The only “shenanigans” going on here is businesses willfully disregarding the intent of the law in furtherance of maintaining a status quo in which job seekers are at a significant disadvantage.

Understanding the Bogleheads philosophy is a great place to start. Along those lines, the book “The Simple Path to Wealth”, by J. L. Collins is great for developing an initial mindset on how your money can work for you.

Bogleheads subreddit and forums are generally great. A lot of great knowledge there, as most investors there are familiar with riskier investment as that is how many started.

I have read some insane upvoted comments in r/personalfinance and r/investing but bogleheads are generally on point.

The nice thing about bogleheads is it starts pretty simple but scales into the minutia of various tax efficiency techniques, fund selection, real estate, and so on when you need it.

The other thing I like about it is that the forums have lots of detailed personal scenario discussions that are helpful for getting real life examples of the application of the dogma.
