So much ignorance and snobbery in this thread.
Firstly, it is possible to be happy and to be educated, the two are not mutually exclusive. In fact, it’s more like that we will raise happy young people by supporting them to be well educated.
Being well educated is quite different to being pressured to attain high grades. A person can be extremely well educated without being “top”.
And what we know now is that grades are such a small part of what we need in life. Yes we need to be literate and numerate, and it is just as important to be emotionally literate, to think critically, collaborate, be respectful, and to have a sense of belonging and purpose.
That has nothing to do with going to museums every weekend. Ideally we will give our children wide range of experiences and opportunities, and much of this can be done at a very low cost. The skills acquired through Scouts or Girl Guides, the characteristics of the person who does voluntary work, collaborative skills developed during team sports - all of these are extremely valuable.
And so too is knowing your home is a soft place to fall, that you are loved unconditionally, and making a meaningful contribution to family life.
None of this is dependent on culture or class, it is about being a decent and useful citizen, and a person of integrity.
