Is exclusion from education exclusion from representation?

According to a recent article in the Guardian, ‘only 176, or just over half a percent, of nearly 30,000 pupils who got three As at A Level last year were eligible for free school meals’.

If these statistics are correct, it  indicates that the poorest in society are still not accessing higher level education.   You cannot attend a good university, in most cases, if you do not have good A Levels.

What affect does this have on the media?

If you do not go to University, what chance do you have of working at the BBC or one  of the mainstream newspapers? And if none of the poorest social groups work in the main stream media, what are the chances of a fair representation of this social group?
