Just as are the top executives. And the shareholders that have put money into companies that provide "robots, etc.". All these people, including labor, are stakeholders. If there was 5% GDP growth that got reflected as 5% growth in net earnings for the company, one would expect that all the stakeholders would see roughly a 5% increase in their personal earnings from the company. The dollar amount would be higher for higher earners (5% of $1M is greater than 5% of $50k), but the percentage increase would be roughly in line. The real world results are not even close to this "rising tide lifts all boats" ideal.
In any case, it doesn't follow that wages grow with earnings. Wages have historically been a lagging indicator.
Fair point, though it's not completely clear from the comment.
>Wages have historically been a lagging indicator.
Of course, companies don't know in advance that they're going to have GDP-assisted growth. My point was that growth on the back of GDP growth is a collective windfall, and you'd expect it to be evenly distributed. But it clearly isn't.
All human collective endeavors (with few exceptions) require 3 kinds of human-related input: capital, labor and ideas.
Nobody puts their capital into an endeavor in which the plan is for the that capital to provide renumeration for the labor for more than the shortest possible time (*). The goal is always to generate revenue in sufficient volume to pay for the labor, and when that goal is met, that success is a function of all 3 kinds of contribution.
So no, employee compensation does not come from capital, but from revenue that results from the successful interaction of capital, labor and ideas.
(*) non-profits would be an obvious exception, except that nobody actually talks about investing capital in such organizations, we just make "donations" or "grants". That money plays the same role as capital, however.
