There are hidden rules and behaviors in almost every cultural group from rich to working class, educated to non-educated, young to not young, one region of the country to another, even terrain like lowland vs mountain. Being accepted and having doors opened for you is highly impacted by your behavior and how well it fits in the cultural context - whether it's up or down the economic ladder. So this article doesn't strike me as anything new or surprising. "I think the image that we have—or the ideology, if you want to be political about it—is once you’re 18 or so, you make your own way and your class origin is not an important part of how your career goes from there." I certainly don't have that image - are there those that do? Clearly if you come from a culture of upper / upper middle class professionals you are likely to fit in to that work culture more naturally. If you are not from that culture, then your success at fitting in will depend on your ability to adapt. Isn't this expressed in the idea "dress for the position you want"? There will always be social obstacles. The key is that there not be legal obstacles. This seems pretty obvious. Am I missing something?
