noble we don't just educate our young for what the country needs. By that measure many hard to teach children would receive very little at all.
We educate our DC to the best of our ability because it's better fur society.
As a teacher you must see that every child should receive the education in line with their needs?
Or like bert do you not really see the point of A*s unless they lead to something specific?
But all that aside, it is not just courses in STEM that are competitive. At the most selective universities (and on some particularly well regarded courses at other generally less selective courses) only top grades will get you a place.
Tertiary education is virtually a tiered system and these courses are the top tier.
And it's from this tier that the industries with the most impact on all our lives at a macro level pick the next generation.
Now you tell me that it's not important for that tier to contain the very best minds we have or for that tier to include people from all sections of society.
Currently we leave this field far too open for the posh boys ( and it say that as the proud owner of one myself).
