I don't think he meant there is no opportunity for black people, but that it's truly a "land of opportunity" only for whites (more specifically white men).

Like, I grew up in a lower-middle class family and flunked out of college due to my f-ups. I squandered a lot of opportunities through my 20s, and yet still ended up in a position where I could teach myself to become a software developer, and make good money today. I got a lot of extra chances, chances that people of color don't necessarily get.
