Corporations are just the way the owners of capital organize their money.
When you see the physical location of a company, its facilities and offices, equipment, machinery and vehicles, its goods, etc; you are looking at the manifestations of the capital of its owners.
Money became an office, it became a facility, it became machinery and vehicles and so on. When you look at a company, you are looking at the money of its owners and investors. The money they have invested, and the potential profit which encouraged them to invest in the first place. You are looking at the assets and instruments of imperial power.
The capacity and efficiency of production and distribution, the effectiveness and reliability of the supply chain, the stability of operating costs, and so on; these are all part of the formula for fortifying the power of the owners of capital.
