The reason is that your question makes no sense, and shows a lack of understanding of how markets operate.

Corporations work on markets, with customers, and need to dynamically adapt to the demands of the customers. Therefore the concept of planned economy goes out the window.

Leaders in a corporation are accountable to the share holders, so again, what you say makes no sense.

Morality relates to value carriers, in the form on conscious human beings, it has no relevance to "the corporation", so for ethical questions you ask the person.

I know you will never research this, but for others who are interested in the only ethical and realistic system to govern society, libertarianism, to great places to start is Johan Norbergs The capitalist manifesto, and Ludwig von Mises Liberalism.

To me it seems that in the end main measure is how deep/powerful are hierarchies in a system. How much power has one individual over the other.

Many libertarians and liberals believe that it's the freedoms one has that make system anti hierarchical.

But as you point out when you have absolute freedom in market based society then you eventually end up with intensely deep hierarchies.

In other words you are free to do everything but there is no guarantee you can do anything - even the most basic things like get food or shelter. And most end up with the short side of the stick.
