The book wasn't a compilation of independent research papers. It was produced out of a compilation of interviews done to better understand millionaires.
Support was defined by the wealthy parent providing financial support, whether through a stipend, gifts, or whatever. It turned out that, despite the best of intentions, such support almost inevitably wound up with destructive emotional dynamics.
What’s an example? I thought the family safety net was a bigger factor in children from wealthy families starting riskier ventures earlier in life and perhaps serially. I’ve never heard of a company starting like you describe so I assume it isn’t that common, but maybe people just don’t talk about it much? Or maybe you are just exaggerating the loan magnitude by quite a lot?
But presumably it is also possible that some children were smart and successful, so therefore the parents didn't feel the need to provide so much support.
Whereas others were perhaps struggling with everything so the parents gave much more support.
Everyday example: the parents of disabled people dedicate almost everything they've got to help their children, and often end up poor and with a poor quality of life themselves as a result.
