It is not only natural, but one of the critical reasons for human survival is that we band together and project power in a concerted way against the things that may pose peril to us. It is the force of numbers that allows cultures and groups to survive. The “rugged individualist” is really only possible with prior establishment of a strong group with collectivist tendencies.
So what is the problem with concentrating the force of human will. Most people are generally concerned with others and can be trusted with the reigns of power. The problem with focused power tends to occur when the centralized authority looks to expand, or defend from perceived threat. There are also opportunities for individuals to indulge should they possess the propensity for such behavior and find themselves in control of a powerful apparatus.
Many areas of concentrated power can be destructive to individuals that are not necessarily in violation of generally accepted moral principle.
One of the typical concentrations of power is business. Large corporations tend to make soulless decisions that can have very damaging effects to those with the least amount of resistant force. Most of the time, it is financial impoverishment that is the greatest fear here, and all of the things that can happen in the chain of circumstances derived from the impoverishment of potentially large groups of people. It seems that the re-allocation of resources toward those with the ability to work within corporate structure tends to be both motivation and eventual outcome should no coercive force work in opposition to innate human drive.
While this is a concentration of power that can be said to have both good and bad results, there is no doubt that there are greater powers in the world. No corporation can withstand military opposition, indeed most cannot even withstand the backlash from large segments of the population.
Another common concentration of power involves religious institutions. Religious institutions have, over the course of centuries, been a highly impactful area of concentrated human power. There will always be a segment of the population that will be zealots regardless of the particular stripe of religious belief. There are currently a group of men called “morality police” in one particular theocratic part of the world. Many religions call for death to vocal non-believers, and have the power to enact such disgraceful abuses. Almost no religion has seen long term longevity without an abuse of those outside the group of core believers.
Of course, the greatest mass murderer in history is government. Sometimes the previously mentioned concentrations of power manage to gain control of the true demon. The establisher of law and controller of military can find no equal in either the religious institutions or the corporate power centers. That is one reason that we may see each of those types of organizations assume control of the real power. Governments allocate for themselves the right to take life or property without consequence, so long as power is secure. It is and always will be the biggest bully on the block. This is one reason that the founding fathers of this country sought to cripple its ability to project power without gaining full consent from the governed.
