This is typical of the Heritage Foundation and the Cato Institute. I was linked to a Cato paper which claimed the productivity/wage gap doesn’t exist. It claimed the additional value of non wage compensation completely removed the discrepancy. After a few paragraphs of variables and equations, buried in a footnote at the bottom read: “There is no number reference for this value.” Basically they gave a detailed report about how making up a missing number balanced the equation.
