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.
Arguably the most capitalist societies were probably nomadic hunter gatherers where everyone was always on the move, every man and woman was out there for themselves. Not really everyone's cup of tea let alone particularly enjoyable to be fair
There’s no evidence of any time when humans were “Out there for themselves”. History shows definitively that humans have actively collaborated in social arrangements in every instance that we have found.
Sounds like somebody needs to take an anthropology course or two. You are badly confused. You're not even wrong, you're just light years off base and clearly speculating with a kind of pure almost childlike ignorance of the subject.
