That’s not what they said. They were commenting that comparing payroll to revenue is like comparing apples and oranges. If you make an apples to apples comparison, like between payroll and profits, you can make a more defensible argument that income inequality is a problem which needs to be fixed.

Misrepresenting the issue causes people on the side of labor to be less effective in their efforts, because they’re operating with flawed data, and makes it so that people on the side of capital can more easily disregard the concerns of labor.

There are solid and useful comparisons to be made, as I previously mentioned. Worker salary vs. corporate revenue isn’t one of them.
