Extreme wealth inequality has historically led to social instability, so there’s that.

none of this speaks to the 'problem' as it relates to race manifested in 'white ownership'

I hear you. I took the point as more of a, "if we want to realize more diversification of wealth and a more representative distribution, ..." I normally pick on stuff like this too but I'm willing to give the author the benefit of the doubt and not assume they're racist because the article is so well written.

In US society, wealth is power. When there is a great disparity in wealth, there is an equally great disparity in power. It's that power disparity that is a serious problem, not the wealth as such.

But again: why is it bad if white people are in power? What’s wrong with white people?

I didn't take the line as meaning what you're taking it as meaning. I took it as as a recognition of the makeup of the traditional power structure. It did seem a bit on the pandering side, though.

There's something wrong with capitalism, and radlib journalists are somehow getting dragged all the way into advocating worker ownership without actually realizing it's about the capitalism, not secretly about race.

Ideology is a hell of a drug. Most of the ruling class and elites still believe There Is No Alternative, so this is what we get.

So the ruling class simultaneously believe that There Is No Alternative, but also that giving workers (partial) control of the means of production is a good way to Smash The Patriarchy?
