Deep-rooted through slavery, self-hatred
The Jewish stick together, friends in high places
We on some low level shit
We don't want niggas to ever win
Nas is saying African-Americans try to sabotage each other, to stop them from gaining success, unlike the Jewish, who help each other out with their status in society.
Might be de-rooted through slavery, since slavery took them away from their home and everything they were used to. The slavery is just like girlfriends/wifes that gets abused thinks they desereve it. That´s why they can´t see themself as bosses, blacks sees themself as worth less then white people. Could also be a reference to the Law of Attraction that you have to believe in yourself to succeed, blacks don´t do that because slavery.
Blacks are still in chackles, but in their mind instead. That are just as powerfull as real chackles.
