I agree. To me, the post reads a bit like this: "Back then, we did not have as much inequality, but the super-rich did not deserve their wealth. Now, we have more inequality, but the super-rich [like PG himself] really deserve it, because they are innovators." The post does not cover the arguably more important questions like "Are the working and middle classes better off?", "Was there less innovation back then or were lesser paid innovators just as innovative?", and "Can we have as much or even more innovation with less inequality?".
