I know that when I was looking to do my first degree it was 'proper' subjects like Law, Economics and Medicine that were to be considered and anything else was seen as 'playing'! When I chose to do Politics and Japanese most of the people in my family asked things like 'So...are you going to be a politician then?' And 'what do you want to learn Japanese for?'
When I topped this up with a Law degree, relatives and family friends (African!!) were more approving!
Usually when it is said that so-and-so's son/daughter got a first or distinction, the praise starts until the question of 'what was it in?' is posed and the answer comes back as 'Media studies' or 'Sports science' and then it wanes slightly.
I think that although there is still that 'pressure'/'assumption' that you will study a 'proper' subject at university (if you are 2nd+generation African anyway), parents and individuals are abit more adventurous with their degree choices now.
As far as what issues...money and the potential to get a job when you finish. It may be nice to do 'History of Art' but unless daddy owns an art gallery, how the hell are you going to pay off those student loans you have accumulated in the 3+ years you were at uni? I chose Japanese mainly because there was a gap in speakers at the time and this has paid off....the fact I am Black just adds a twist!
