From the framework of what things were like in 1787, things may be slightly different now, but taken from the perspective of, say, a couple thousand years, people behave in largely the same manner, and those with the means and motivation use the alleged power of the collectivity of State to assert their power over the general population, same as always. That things have always been this way isn't evidence that everyone in power in history has worked in concert with everyone else in power (which I don't mean to say that you're saying they have), but rather evidence of human nature. Our behavior, as individuals, and as a species, is hugely predictable because it is always determined by the same factors.
doesn't need to be a justification for anything. To me, it's a logical reason to assume that they will continue to put up with bullshit, just like they always have, and always will. I don't see any particular need to take on the impossible task of changing any of it when I can spend my time how to best make it work to my advantage, and bide my time until I die.
