This paragraph is from the article you posted.
Sterling got rich because other Jews helped him when white people did not. When he finished law school in the early 1960s, Sterling had to start his own business because white law firms wouldn’t hire Jews. As a result, he became enormously wealthy, largely due to the support of other people in his own community. This is what gave him the power to singlehandedly purchase the NAACP, an organization that represents a community that would rather give its money to whites than to itself.
It clearly states that other Jews within the community helped and supported him, not that they were wealthy. He is just one man who became wealthy but he also had something to build with, ( A Law Degree ).. We can talk about what wealthy people are doing or are not doing to help but the bottom line is what are folks themselves doing to change their situation.
In addition, there are over half a million Jews living below the poverty level in America. I guess they forgot to lend a hand to these folks......
