> The United States is a flawed system designed to protect the feudal, mostly southern property based system A lot of the constitutional factors you object to - like smaller states having voting power out of proportion to their population, or the constitution being difficult to amend - are also shared by Australia, yet Australia never had race-based chattel slavery. (Dispossession and maltreatment of indigenous people isn’t really comparable because (a) the US had that too and (b) to the extent that influenced the constitutional architecture, it didn’t really influence the aspects you are complaining about.)
