Read that carl marx book with engels, or just listen to the 1 hour audio book.
Capitalism is inherently exploitative, and this is not coming from some socialist but a business major from a top globally renowned business school whose worked in mining, banking and venture capital and has his own business with real employees and substantial capital flows.
In my view, black people do poorly in capitalism because we are not exploitative nor exploiters. However that to a large degree is the underlying foundation of wealth. I also believe we have artificially limited our capacity due to colonialism and enslavement. We think of being the actor but not the producer, we think of working in the bank but not owning it, we think of being a singer but not the music manager or owning the record companies and distribution, we like to buy consumer goods but rarely open consumer goods stores.
In my opinion, if African peoples changed their general disposition away from consumerism as in buying things to selling or producing things, they'd improve their financial position substantially as a group. Forget working for white people, they don't like you, that is why you are the last hired, first fired, and treated like dirt on the job.
to be successful in business you just have to have workers produce a product, sell that product at a higher price than it cost to produce and then in turn repeat the profits.
