What you are saying here has NOTHING to do with wages.
Wages are driven by market forces, not by CEO directives.
What I think you are failing to account for is that the 7% that
@Half Fast is referring to who moved upwards out of the middle class did so because THEY were the ones driving the productivity gains. The people in R&D, manufacturing engineering, automation systems, process improvement, and similar areas are the people who improve productivity. The capital used to fund the investment in productivity gains comes from the shareholders.
Think about it for a moment. Consider a machine operator who runs a machine that can product 50 widgets per shift; he works 40 hours per week. After 3 years of development and $2M of investment, the manufacturing engineering team installs a new machine that they designed which outputs 150 widgets per shift. They train the operator, and a week later he is running a new machine and producing three times as many widgets....but he has gained no new skills, he is not working any more hours, and the difficulty of his position has not increased. The manufacturing engineering team, however, has created a whole bunch of value in their machine design, and now hires an additional junior engineer to maintain the new machine. The engineer who came up with the concepts at the core of the machine gets promoted and gets a healthy bonus, pushing up his income. The investors get the ROI for the $2M that they invested, and it is returned over the next several years. The VP who suggested and approved the project gets a slightly larger bonus, and the CEO gets to keep his/her job because the company hit their earnings targets.
This is how it works in the real world.
