If you want to work high up in retail then go for it. I don't see the point of going to uni for a degree then into something unrelated. English people have to pay for uni so I think its completely backward to do that. What a waste of money.
A degree is no indication of how many facts you know about your discipline, in fact most of the stuff you learn is theory based and doesn't really apply to the real world which is why people like lawyers become bankers etc.
What a degree teaches you to do is examine things more critically, be able to stand up in front of a large audience and deliver a good
presentation and the understanding of how to source the best information for your work. These are key job skills which will allow you to be promoted much quicker in any organisation than those without these skills.
It really is no mistake that people with a degree STILL on average earn more.
and harrods must be the only stuck up company to not allow tattooed people into there offices.
I very strongly doubt that.
