First, I'll recommend Discrimination and Disparaties by Thomas Sowell, another fantastic work from Sowell put out this year that builds on some ideas from previous essays. It's short, but the arguments are concise, empirical, and convincing.
And 3 books that have most recently made it into my "must-reread" category.
I grew up on Thomas Sowell. Extremely articulate economist. I've now come to disagree with probably one-third of what he writes but all of his works are really good frameworks of how to think.
I wouldn't want to read someone I agreed with 100% ;)
I really like Sowell's writing style and willingness to tackle issues in a straightforward way that others skirt around. I still have many of his past writings to get to, as I only recently started reading him, to my own detriment.
We're blessed to have nearly 50 years of his writing and that he's still at it at 88.
