Fridge, I don't agree that there is a feeling on this thread that a taxi driver can't be cultured. Many posters, including myself, have said that the view of WC people as thickos is insulting. I personally posted about my WC background filled with books and politics!
What most people have said is there is less likelihood of WC people being exposed to certain things because of lack of opportunity, money, contacts etc!
Agree that many kids won't think certain jobs are for them because they can't identify with the people doing those jobs. But I know for a fact that a lot of WC people don't know certain jobs exist. Not doctors/lawyers etc, but some more less-known MC jobs that you might only hear about because your parents friends/neighbours etc do them. So unless you have very good career guidance, lack of knowledge in that area is another barrier.
I'm a lawyer from WC background with a strong regional accent by the way, on a separate point! I've even been let loose in court! But it's harder for me to prove myself, without a doubt, and I've been made to feel and have felt inferior.
