Successful parents give their children all sorts of advantages: they stimulate them intellectually, expect them to behave well, feed them well, educate them, surround them with books & conversation, teach them to read early... You could call those parents "intelligent", though not all of them would do well in an IQ test, and not all of them are rich. But they are successful as parents. You can account for all the strengths of the children by evaluating their environment.
And of course wealthy parents produce wealthy offspring by showering them with advantages: money, education, contacts, trust funds... Would you claim some genetic component there, too?
There are very clever & wealthy parents who are emotionally stunted, who produce damaged children, too - but sometimes those children survive amazingly in tact.
And not all successful parents have successful children, any more than failing parents have inevitably failing children, although there too the effects of environment can be huge and usually unfortunate.
Many of the twin studies used to justify the relationship between genetics & various forms of "success" have been debunked, by the way. They simply do not stand up to scrutiny.
Then why do intelligent parents tend to have intelligent children?
