You know what, coldtits? All those things happened to me, and yes, it was awful at the time. Both parents died, I had to leave the private school I was at, ended up going to a failing school where I did regularly get the shit kicked out of me on an almost daily basis for no other reason than being "the new girl who thinks she's better than us because she went to private school" - that's why I intensely dislike the blanket attitude that some have applied to people that just happened to be born into circumstances different or apparently more affluent than their own. I had to use the public library to educate myself as opposed to the resources the school had. I eventually ended up homeless and it felt like life was over.
I of all people can see why some people sink instead of swim. But, having come from that, I truly believe that, in life, it is possible in more situations than people imagine to make your own luck. TheseThingsAreGoodThings is right when she says that in the popular professions she lists, it is not about who you know but what you have done and can do - getting through the recruitment process, especially for something like law which I'm going into is daunting, but the information is out there as to how you can do it and a lot of that information is freely available. Some are successful, some aren't, and that success is definitely not limited to who your parents know or how much your parents earn as some people on this board would like to presume/believe.
What I keep trying to say is that it is easy and convenient to simply point and say - well, his/her parents had money and that's why they do well. It just isn't as simple as that.
