The article makes some great points, and more people should read about Piketty's research on wealth concentration. But it buries the fact that buybacks have actually been decreasing by certain metrics [0].
Granted, much of this slowdown is due to Apple waiting for tax law changes before moving money around. But an article that uses six-year-old statistics as its lede, but doesn't even reference recent trends, should raise red flags about its impartiality.
