Democracy IS best. We arguably don’t have it because capitalism is pay to play and money equals speech = the orgs and individuals with the most money have the most influence over politics and government; so much so that wealth essentially controls policy — note that despite the USA being one of the most obvious and egregious examples, the problem is not isolated in any way shape or form.
If there were hard limits on individual wealth, every business was a co-op owned by the workers, and their influence on society was properly regulated, maybe we would have much more egalitarian democracies, but individuals and orgs will always strive to corrupt the system for their own power/wealth advantage (incl under any other system e.g. socialism).
