What a good question and I can only answer it from my point of view for I have not done enough research and it really reminds me of degree type questions…. 😉
I believe that the socioeconomic background has an enormous influence on the child’s academic achievements. We shall leave aside the odd farmer’s son who goes to Harvard if you will! We shall also leave aside the fact that some high IQ children (and thus parents) come from the ruralist areas, thus we shall really talk about the majority of cases.
I think we all have knowledge and a brain to begin with that is NOT the same, we are not all equal and to make everyone fit into a particular mould is wrong – again my view. We can however all shine at various levels, can we not? And I believe it is this that is important here, in life.
In this digital economy that is coming upon us like a tidal wave, we know nothing about anything! This ‘old’ school question is not of the essence of life today. For perhaps things that were of “lower” socioeconomic standing yesterday is of better use tomorrow.
That being said i believe academic achievement is also dinosaur age 😉
Gone are the days of Oxbridge or Ivy leagues or Grandes Ecoles ruling the place, now college dropouts are making things happen – Sir Richard Branson, Tony Robbins, Robert Kiyosaki, and even my mentor
The really lovely thing about the new digital economy is that it is one of exchange and giving value. The more value you give the bigger the paycheck – that you write yourself, no longer dependent on a boss!!
You are dependent thought on education still – to learn will not go away. And you can learn many different ways so I believe the socioeconomic background of the parents to not really be such an issue as before. Everything will be online, and most importantly it will all depend on YOU and your soul. This has been so neglected of late that any ‘bizarre’ kid will stand their chance, and more 🙂
So I suggest you look up thisstuff on my website and make a new life for yourself – be prepared though to have amazing paradigm shifts!
Enjoy the journey
