My Quest for an Introductory Understanding of Modern Economic Theory

On March 26th of this year I ran a search on Amazon for capitalism and my first result was Capital in the Twenty-First Century, which had come out just two weeks before. It sounded exciting (and infuriating and impenetrable) but since I couldn’t find a copy in Austin’s public library system, I wrote it off for the time and started clicking through the recommended also-boughts. I compiled a list of similar Serious titles that were available and left for my day job. Two hours later, on a break, I opened Twitter, and the top item was a headline from The New Yorker: "Piketty’s Inequality Story in Six Charts." Was I baader-meinhoffing, or was something serious at work?
