The first thing to acknowledge, is that corporations, are artificial creations of the state and thereby they should always be beholden ultimately to that which created its existence, in the first place. However, even the most cursory investigation, demonstrates that corporations and thereby corporate power has never been stronger than it so is, today, and of which that corporate power reaches into every meaningful sphere of governance within America. In fact, the argument could be made, that rather than seeing this country as being a nation of, for, and by the people; it is more times than not, the governance of, for, and by corporate power.
There are two very valuable things that corporations have, that human beings either lack, or will ultimately lose personal control of. The first is that unlike human life, corporations as adjudicated at the present time, are perpetual in their existence. That is to say, while there is a know creation date, for a given corporation, there is no set time or conditions thereof, in which a corporation will ever cease to exist. In other words, the most successful corporations, do not follow in kind with the seven stages of mankind, as so written by the brilliant bard; but rather, the best corporations as they age, are able to not only adjust to the times, but rather than getting feeble, they often instead, get even stronger. Additionally, when a given wealthy person dies, what they so had as material assets, are going to be subject to all sorts of applicable taxes, including estate taxes; whereas, because a corporation never dies, this thus signifies that this artificial creation of the state, is never going to be subject to estate taxes, and therefore the most successful and powerful of those corporations, will continue to grow their assets, and their footprint, year after year, only being subject to the vagaries of their particular business and the overall economy.
All of this basically means that while we can rightly decry family dynasties, of which, that money, power, and assets are passed on from one generation to the next -- that somewhere along the line we seemed not to have recognized that as much wealth as a given family dynasty so has; it absolutely pales in comparison to companies such as Apple, which has a market capitalization worth of over $2 trillion, as well as having over $200 billion in ready cash and investments. This so indicates for these superrich corporate behemoths that what they so want they are going to get, for the only entity that can conceivably hold a candle next to them, is their own government, which seems rather to be their enabler, more than anything.
Those that believe in good governance, democracy, representation, and the like, should be rightly concerned about the ever-growing amount of corporate power and influence. Those then, that believe that what is good for a given dynastic corporation must be good for the country, are either delusional or fooling themselves, for many of those same corporations are only interested in one thing, above all, which is the making and the extracting of more and more money from those that they see as functionally their subjects and nothing much more.
