If you like anecdotes on how some famous successful people brought up their kids, here are a few.
John D. Rockefeller Jr. was given an allowance as a kid. His father didn't care what he spent it on, but he had to keep proper double-entry books on all his transactions, and these were audited monthly by a professional accountant.
Henry Ford II, as he approached driving age, was bugging his grandfather, the original Henry Ford, for a car. He was told he'd get one on his birthday. So, on the appointed day, there was a completely disassembled car, along with all the tools needed to assemble it. It took Ford Jr. about 6 months to get it assembled and running. (Incidentally, the reason Fords still run Ford Motor is a two-tier stock scheme, like Google and Facebook. For many decades, this was very rare, because the NYSE didn't allow multiple classes of common stock. Ford was one of very few exceptions because its founding in 1903 predated that rule.)
Athletes seem to have have children who do well in athletics; there are three- and perhaps four-generation families in major league baseball, and the NBA has had several two-generation families (Bryant, Barry, Curry). In the arts, one sees less of that. In painting, I can think of the Lippis, in writing I can't get much past the Amises. In the sciences, I can't think offhand of any such names, though I expect the better informed could.
There's nothing novel here.
It's just strange to see the the explanation spelled out clear as day as to why adolescents turn to drugs, but only have it apply to affluent white children. It's almost as if people and those who conduct studies are more sympathetic to people they can identify with.
But bad parents are bad regardless of whether they are present or absent.
