Some people are born rich or moderately rich, some are born middle class and some are born poor or extremely poor. All these conditions come along with a set of survival guides that the parents, relatives and even teachers will pass along as a map of life. For example, in a school of a country that does not give opportunity to its people, where most of the students are poor, it is unlikely that the teachers will induce them to think big or have big dreams...more likely they will aim to keep them apart from drugs, avoid problems with the government and try to imbue some basic skill for life. The ultra-poor do not even get that - which actually may be better.
In a preppy school, where most of the students are rich-born, the conversation is quite different. Culture, life, opportunity, spirit-de-corps and class mentality are imbued in the same manner, so the kids will somehow justify in their minds that they have the right to be rich even if they have not done anything for anyone in their lives - perhaps not even for themselves - because of some Darwinian property of cosmos.
As a result, the poor and even middle class have to jump over one real barrier, their lack of funds, and more importantly, like the Elephant that learns young that he cannot break the chains and never tries again, over their own state of mind, their own prison set by the terms of those who trying to help taught them to avoid anything but doing the same that keeps them poor.
I somehow agree with some of your statement. I was raised in a middle class family where studying is a priority. In school we are taught how to follow rules and regulations and for me its a preparation for us to become a good workers. We are taught and being mold to become workers and not to reach the highs. It is hard to fight back in this manipulation by governments, its like we are destined to work for others and not for our own selves. By this, it's just a matter of dedication and skills to set free to these chains and build your own legacy. It's up to us whether we work for others or we work for our own company.
