When the US Constitution was written and adopted, the process was not unlike how politics is done today. There is a tendency for people to believe that somehow back in the ages of antiquity, in this case, the late 18th century, when the founders of the republic met to draft and adopt some sort of framework for what they intended to establish, it was a process driven by some sort of mythical pureness. It is assumed that these men were all above petty infighting and squabbles, and partisanship; that they were statesmen as we are told and that means they were somehow above all of that.
That idealized view is simply not the case. When they convened to start work on the framework that would finally emerge, they did not have a clear consensus view of what the final work would be. Many had some ideas, but they hardly all agreed on the fundamentals, much less the details. So, much like today, seriously compromised work resulted.
What all this means is that there was a lot of proposals which some loved and others hated, much deal making and compromise produced considerably less than what most anyone would consider ideal. To compensate for the shortcomings, flowery language was employed to soft-sell the flawed final drafts to those who were to approve it.
So, just like today, there was a significant amount of stupidity and outright corruption coded in the drafts, such that what emerged looked good on the surface, but it was nonetheless, very compromised. It was set up to create one crisis after another, which would eventually lead to pretty much the system we have today, IE hopelessly broken and corrupt.
Since then, the people of our nation have subsequently been programmed to look back into American history and see very little of that. However, we are unmistakenly beginning to see that corruption was there, and is still present in the constitutional system which created our current republic.
