I was on week 10 of writing about it for better developers, and had been giving parts of it to my students. I decided to just break it off into its own sequence. But yeah, the cheat sheet is great!

You know what would be even cheaper? No reporting requirements whatsoever.

The point of regular reports isn't to save (or spend) money. It's to provide investors with transparency, reducing fraud and improving the overall market.

It's no surprise that a grifter like Trump hates such reports.
