[The Urban Sombrero]

You said economic injustice, not even remotely the same thing.

The rich will fare better for a little while, more so than everybody else. That happens in every war and has nada to do with the balances you mentioned and the fact that the black horse means simply that famine is coming. Another portion of 'standard commentary' mentions the fall of Babylon, or the financial system of the whole world, which will crash in the space of one hour.
Revelation 18:10-11 (KJV)
10 Alas, alas, that great city Babylon, that mighty city! for in one hour is thy judgment come.
11 And the merchants of the earth shall weep and mourn over her; for no man buyeth their merchandise any more:

The rich man did fare better than the beggar placed at the mansion's gate. True enough.

The bounty and consolation of this earth's treasures don't spend beyond this temporality, unless they are used in ways consistent with the kingdom beyond. Economic injustice is a big deal in Scripture. I'm not moving from that. I'm also not suggesting that "white people" as a monolithic group are responsible for poverty amongst black people. The ways and systems of Babylon are more complex than that, in my view.
