I have no intention of sounding mean or vicious, but, "ironically" speaking....
Corporations and Banks are so effective that they leave people available to enjoy themselves doing whatever they want wth lots of free time, while they and their employees secretly feel special because they do all the work, which seems something commendable. ( but hides the fact that all they want is to win all the money.) So much for corporations effectiveness and 'specialness', within the context of human evolution... globally we see no facts that can prove that 'specialness'. Something being Natural does not mean that it is Common Sense. Long road ahead in terms of Human Evolution!! We have barely started evolving... for Real!
"Specifically" speaking....
The presentation each one puts in place 'for others to see' specialness, mirrors the desire of each one of being special. Corporations and Banks have this awesomely effective advertising 'machines', that seek out all the weak points of the mind of humans, to seduce them into buying their product.
To hide all that, the 'presentations of self' (self is the corporations, corporations are a symbol of self as you said) commonly use excuses such as saing that their work is beneficial for society when in fact, only self interest is actual verified as doing anything for profit.
The profit represents the individual ego of each one, when each one thinks he needs to be more than others to be respected, because he thinks all think the same. That is the essence of spitefulness.
If we notice how companies have been advertising their initiatives in this world we find that it is common to use such presentations pictures words that appeal to global benefit, but if we look at the world, we see that that benefit never really becomes real.
All this happens due to the starting point of the companies, mirrors the individual self interest. They actually survive based on that. I find this very prominent point in market studies when people want to create a company. Much of the fundings that new companies get, is based on how good are the prospects of getting products selling is, to an not yet explored market (market in this context means, potential consumer group). Never the less one rule of thumb when considering creating a new business is to create something new never seen before, since the ego of man individual adheres a lot to what is new, never seen or accessed used by others before.
Corporative competition is also seen as a legit and perfectly normal/acceptable behavior, since it mirrors exactly how the human's individual mind works in terms of individual survival.
Obviously in all of this, there are some companies that do work that is somehow required and beneficial to all, but much more are the cases where products are only created to satisfy the individuals needs wants and desires of the mind and ego that each each one of us has in his secret mind.
