Justice Ketanji Brown Jackson is former House Speaker (and current Fox News board member) Paul Ryan's sister in law by marriage.
I'm not saying she didn't work hard to develop her Leftist belief system under commie professors, but let's acknowledge that well connected family in high places also has its privileges.

From the NYT in opinions in which the two black members of the court disagree with each other:

"Justice Thomas castigated Justice Jackson’s backing of affirmative action, describing it as a panacea where society would “unquestioningly accede to the view of elite experts and reallocate society’s riches by racial means as necessary to ‘level the playing field.’”

Although he acknowledged that “our society is not, and has never been, colorblind,” he deemed wealth gaps between Black and white Americans “constitutionally irrelevant.” In Justice Jackson’s view, he wrote, “almost all of life’s outcomes may be unhesitatingly ascribed to race.”

How it feels to have your life changed by affirmative action.
He then hit on a recurring theme in his writings and speeches over the years: his anger at Black people being portrayed as victims.

He repudiated statistics showing that the average white family makes much more than the average Black family, arguing that such figures unfairly portray Black people as a monolith.
“This lore is not and has never been true,” he wrote. “Even in the segregated South where I grew up, individuals were not the sum of their skin color.”

He cited a 2016 book by Thomas Sowell, an economist and prominent Black conservative who has influenced Justice Thomas’s philosophy, and he accused Justice Jackson of using “broad observations about statistical relationships between race and select measures of health, wealth and well-being to label all Blacks as victims.”

He continued, “I cannot deny the great accomplishments of Black Americans, including those who succeeded despite long odds.”
Justice Jackson’s viewpoint, he said, would keep Black people locked into “a seemingly perpetual inferior caste.” He called that “an insult to individual achievement and cancerous to young minds seeking to push through barriers, rather than consign themselves to permanent victimhood.”

He also wrote that she was drawing on “race-based stereotypes,” when, in reality, “all racial groups are heterogeneous, and Blacks are no exception — encompassing Northerners and Southerners, rich and poor, and recent immigrants and descendants of slaves.”
By “articulating her black-and-white world (literally),” he added, Justice Jackson ignored the experiences of other groups, including Chinese immigrants, descendants of Holocaust survivors and those who came to the United States from Ireland, fleeing famine.

Justice Jackson pushed back sharply against Justice Thomas, accusing him of imagining her viewpoint and misunderstanding the underpinnings of her support for the policy.
“Gulf-sized race-based gaps exist with respect to the health, wealth and well-being of American citizens,” she wrote. Although those disparities emerged years ago, she added, ignoring that history would be foolish because those inequities have “indisputably been passed down to the present day through the generations.”
