I get what you are saying. It is a difficult question, but it is simply not present here. Let me try to explain better. These numbers are for illustration.
Let's say that, in 1973, a worker produced a $10.00 of output per hour. The worker was paid $5.00 an hour.
Today, that same worker produces $40.00 of output. The worker is paid $10.50 an hour.
The company takes a greater percentage. That's what this study says and it is true without having to look at those other things.
