Do we need a uniform society to have a functional democracy?

Here are some points we made during our last democracy discussion: (Boaty McBoatface) I want to talk about the things we mentioned and bring them along further, using this as the focus question:

“Do we need a uniform society to have a functional democracy?”

—Basically, we need to have a consensus to erace racism, or a consensus on how to treat social inequality, but there is no consensus now because we cannot guarantee who we are dealing with.

—In capitalist society, since there is no equality of resources a person can obtain, no equality of wealth, no equality of education, people have to strive to climb up to the highest level in society so as to acquire all these things. And also, because of limited resource, people compete to divide their own territory in society. As a result, hierarchy is formed.
—‘Their own territory' refers to a vertical one not a horizontal one, because the place we can live is too small ha

—The fundamental question of society or politics is, are you one of the masses, or are you separate from the masses?

—Crowds presents power that can’t be controlled or predicted. But democracy is predicated on crowds. We fight together for the future. But at the same time I don’t trust the masses, because of the tyranny of the majority, the ignoring of subtle differences.
There’s a famous poem by Ezra Pound: “The apparition of the faces in the crowd, the petals on the wet, black bough.” He’s talking abouthe crowds in the Metro station of paris, it’s the character of modernism.
We know now that Pound became a fascist, but the fascist attitude towards crowds is complicated. They relied on the support of the crowd to get power, but they have to control and manipulate the crowd to stay in power.
—That’s powerful, though, that’s the same power as democracy

—How do we make government responsive to the needs that people actually have in the world right now? Does it do a decent enough job already? What could improve?
