When I studied macroeconomics, my sorrow was that it wasn't macro enough. Umair Haque went much farther into the field than I did, and came to the same conclusions, except with more basis for them.
He's now writing big essays that can't be categorized, and are wonderful. Try The Beginning of the End of the World. I want to be one of the people who comes up with the visions that he is calling for.
He's also written a book on leadership that can be read in chunks.
When he calls himself a "vampire" he's not being sarcastic; he's extremely allergic to sunlight. If you read enough of his stuff you will get to that story.
