Economics in One Lesson is so cogent that it will, I think, let you absorb a great deal. And then the Creature from Jekyll Island, which is really a history book that reads like a thriller, will let you see how the departure from economics has had an effect on the country-- an effect the most recent version of which you correctly identified. (Which was impressive, frankly, can't tell you how many times people argued with me about house prices between 1998-2007. Sadly, going back to them in 2008-2010 and saying "See, I was telling you this!" didn't earn any kudos for my having called it correctly... I think their worldview is plastic and easily gets remapped by TV news.)
Anyway, the departure from economics is for very sound reasons-- it profits the people who are peddling the bad stuff. But that also means we can profit from it too.
Anyway, I just wanted to give you the books I thought would be most effective for you. I read a lot of investment books when I needed to learn how to invest (Vick's books on Warren Buffett I found particularly interesting-- now I calculate what my return will be before I make the investment. People assume that buying stocks is really risky, but the reality is risk is quantifiable. I can buy a stock and know that I will be able to sell it for a specific price at a specific time-- you can calculate this!)
Anyway, good luck! I admire your datamining-- there's a lot of opportunity for you out there if you keep that up.
