Also, somebody else just submitted this [1]. The Fed just released a paper showing (or at least affirming) that the labor share of income in the US is at its lowest post-war level which is, more or less, equivalent to stating that it's at its lowest level ever. They're likely just using data starting at the 40s for the same reason I am.

But the really interesting thing? Go open their graphs and look where the inflection point is. It's, again, the funny money.
