Without the laborer, none of those things or components or supplies and materials etc you mentioned, would be available for the rich man to buy to start his new business.Simply not true.
Labor is one of the values.
But without the concept of a business, no product is created.
And, without the raw materials for a business, no product is created.
And, without the refining of raw materials for a business, no product is created.
And, without the machinery to put the refine the materials together for a business, no product is created.
And without the plan to acquire all the needed components for a product, no product is created.
I agree that without the labor, all of the above is meaningless.
But, still, without the acquisition of the plots of land to build the plants and offices and then the construction of those plants and offices, no product is created.
Then we can talk about the obviously necessary distribution and sales of the product without which, the creation of the product is pointless. And if it’s pointless, the company ceases to exist because no income flows in.
And if the company goes out of business, no labor force for the company can be maintained; and, labor becomes unemployed.
You can own a mountain of granite, or a field full of clay, or a forest filled with wood or caves filled with gold....or land rich in oil....
All of it worthless, without the laborer....to retrieve it for you, to make it in to a widget to sell for you...
We, the laborers, are worth more than you, and we all collectively realize....imo.
When we produce more than what the owners are paying us to make it, or do it, that becomes the owners profit...in the simplest of terms.
As our productivity increases, we the worker, are making the company more profit....especially if our salaries are not increased somewhat, proportionately with the increase in what we are producing for them in the same amount of time.
A rich man, could not have become the rich man, without laborers...
