But why was your friend able to spend his every afternoon and weekend studying?
Because he was raised in a supportive, nurturing environment. Probably with grandparents and aunts/uncles to help take care of him. He probably had older relatives in professional careers to aspire to and mentor him. He probably never had to work a job in high school to help support his family, or raise his younger siblings while mom worked night shift. His parents were probably married and able to hold decent jobs to provide a stable home, good nutrition, and a lack of stress. They probably were able to make sure he went to preschool, and had reliable transportation to get him to/from there and kindergarten, and drilled into him the importance of education from a young age. All of these things are what DEI tries to correct for. The people who had none of that never get a shot at redemption otherwise.
The cards are stacked from birth.
