The Democracy of the founding fathers was Greek Democracy, predicated upon a slave society, and restricted to only the elite. This is the society we live in today, even with our reforms towards direct representation. The system is inherently biased towards the election of elites and against the representation of the masses. Hamilton called it “faction” when the working class got together and demanded better conditions, and mechanisms were built in (which still exist to this day) that serve to ensure the continued dominance of the elite over the masses. The suffering of the many is intentional. The opulence of the wealthy is also. This is the intended outcome.
While you seem to be ignoring a significant consideration that sometimes oppression, violence and dominance is a natural human instinct, I do applaud your mindset as a cornerstone of how civil society continues to uphold its virtues, we shouldn't forget that goodwill and faith, no matter how much of it we have in a society, will always be limited and not nearly as contagious a disease as many often hope for it to be, which is why ads, internet memes and newsfeed algorithms have been developed simply to spread such positive messages.
