What does it say in the Bible about inequality?

"My brothers and sisters, believers in our glorious Lord Jesus Christ must not show favouritism. Suppose a man comes into your meeting wearing a gold ring and fine clothes, and a poor man in filthy old clothes also comes in. If you show special attention to the man wearing fine clothes and say, “Here’s a good seat for you,” but say to the poor man, “You stand there” or “Sit on the floor by my feet,” have you not discriminated among yourselves and become judges with evil thoughts?" - James 2:1 - 4
