The thing is, Alan Sugar's life was determined by his parents, family, teachers, friends, innate personality, physical health, and more. No two people are exactly alike, and they'll approach things differently, even from within the same family. I wouldn't just rank someone by their socio-economic position, that would be pointless.
And I think maybe you're missing the point I'm trying to make (or perhaps I'm expressing it particularly poorly) about children.
Twelve year olds can physically have babies. It's not ideal for many physical and emotional reasons, and again this isn't something I'm advocating (my abuse started properly about this age) but they can.
We all socially agree they shouldn't have sex because they could make a choice which hurts them in the long run (whether that's a pregnancy, an STD, or a bad sexual experience, etc). They're too "immature" and perhaps hormonal to make that choice for themselves.
Meanwhile society is fine with a 30 year old making that choice - even if she's had a shitty family, little or no education, no wealth, perhaps significant health problems or lower mental health and "maturity" due to an abusive and deprived life. She actually may have even less "choice" than that 12 year old (who could perhaps reach out to their parents or teachers for support, as I did).
But some people have sympathy for the former but not for the latter who is a grown-up and able to "make their own choices". Because she passed the age of 16 or whatever.
Does any of that make any sense? I might be talking nonsense, but it doesn't feel that way to me.
(I am 100% against child abuse, just in case that's not clear!)
