Any attempt to use the Christian bible to justify massive inequality is a bastardization of Jesus' teachings.
We're not talking about inequality in the sense that people deserve all the same things. Everyone deserves at least to be fed, housed, and taken care of when sick. A society capable of such but unwilling is disgusting.
Maybe you could debate to what degree we could provide for each other. We don't have limitless resources and capabilities. But certainly, we have the ability to provide everyone with clean water, food, and housing at this point.
