We are born into the same world it just looks different to each of us. If you were born in an igloo in the middle of Siberia how likely is it you would be here right now on /.
I'm not talking about genes, just the social situations we find ourselves in the US. If your white access to education and job oppourtunities is a little easier (it used to be MUCH easier). Historically more white families have accumulated wealth; these are the families from which the people who innovate often, but by no means always, arise. How many of the big political families are generational (Bush's, Clinton's, Kennedy's etc.)?
Even 50 years ago just being white gave you far more privilage than today - better access to law and order, assumed correctness in contract disuptes, easier credit. Most of that has been levelled to some extent today which is why Obama is now president - in the long run though he is just a man like any other.
If you were forced to move right now into a town in the middle of rural China how long before your decendents would have: overcome racism; developed language-skills; obtained country-specific education; the political connections and the oppourtunity to run for major?
