Because I did the hard work qualifying whilst earning minimum wage in a call centre, then worked my arse off, took a chance in a foreign country whilst moving away from all friends and family and I do a job that a very tiny percentage of the population can do, hence it being well rewarded.
Nothing to do with falling over the right or wrong vaginas. I saw a good mate on Facebook the other (who fell out of the right vagina and went to the same school and uni as me) complaining about hating his work as a 'server' at Applebys in the States the other day. After uni he went and worked as a ski instructor for half the year and traveller the other half, he's done that for a decade and now wonders why he can't get a serious job. It's all about choices.
I think there's a middle ground between the two.
To suggest that social upbringing has absolutely no marker on success is pretty dodgy. The Bullingdon lot will generally get further for the same work as a council estate kid with smackhead parents, mainly due to the friends they make and the upbringing they had but also intangible things like having emotionally healthy work environments or the ability to expand horizons through the purchase of literature or holidays. I'm not saying it can't be done for people in poverty but ignoring all factors of the development of a person is looking at it backwards.
In these situations I'm reminded of a thing I keep hearing said on a podcast I listen to;"when you're hungry everything else in life pales in importance" which is certainly true. Let's quantify it a minute and suggest that everybody works for 10 hours a day - if you're a kid with a stable upbringing then you can pretty much structure those 10 hours in a meaningful way. Up at 7, lunch at 12, tea at 5, bed at 10. You know the routine so you know the downtime and you know the bits in which you do whatever else you need to do. Kids who don't grow up with a routine or grow up with parents who say tea is at 5 o'clock but then are so wasted out of their minds that the kid is forced to try to microwave beans on toast at 9 at night to get something to eat, they don't have that same opportunity.
Stability in a kids life is ridiculously important. 99% of the kids in the criminal justice system I've had the chance to talk all report the same factors growing up, and it's one that lacks structure and emotional warmth. These things shape the people like become and the students they become thus the workers they become. It's not an even playing field out there. The problem though is that many privileged people who did have relatively stable lives and/or decent educations feel that they are being blamed because they happened to have parents who worked hard rather than pissed it all up a wall. It's not the smackhead kid's fault their parents were wasters any more than it's the Bullingdon kid's fault that their parents weren't.
