I don't recall where I first heard it, probably when I read Cato's Letters or something like that.
But reading about things like Shay's Rebellion ( https://en.wikipedia.org/wiki/Shays%27_Rebellion
) it is even more clear that the Constitution was a coup of the elites (rich merchants and politicians) to create a stronger centralized government. Instead of addressing the problems at Annapolis ( https://en.wikipedia.org/wiki/Annapolis_Convention_(1786)
) they insisted on cementing power in government.
IMHO, all they really needed to do was to figure out a better monetary system, a better taxation system, and reform bankruptcy laws. Simply putting liens on debtors property to be collected when sold, instead of seizing the property, would have eliminated a lot of pressure.
