I don't think you know what you're talking about, you're generalising. It is a defeatist attitude! Should I not try? Should you not try (assuming you're female)?
The American dream isn't a myth, someone like Trump does not represent the American dream, someone like my uncle however who grew up VERY poor in India, went off to the US, opened a restaurant and made investments...he is now living the American Dream with his huge house and his acres upon acres of land surrounding his huge house.
The 2:1 could have been a 1st, that applies to both male and females.
JUST ONE!

As for social class and gender, they cannot be changed but as I said I'm socially left so I can sympathise. But working hard can out do these barriers. If you are good at what you do, who can stop you? Do you truly believe if a woman (who does have to work harder due to her position in the beginning) is brilliant at what she does she will still be on the "back foot"? No, how can you stop somebody who is brilliant at what they do?
I get sexism in the city, yes it exists but should you just sit back and do nothing? not strive after certain careers because you're female? isn't that a bit pathetic? when has that ever worked out well in history? We've over come a lot and it's mostly because people stood up for what they believed in, not sit back and do nothing because of their pre-decided positions in the world .
