Couldn't agree more on education. Putting a strong emphasis on educating your children to themselves be successful must surely be a strong success factor for them - and something they're likely to do in turn for their own children. Conversely, neglecting your children's education is also likely to be passed on, and also likely to have significant effect.

By "education" I don't just mean what happens at school - most school systems provide only the thinnest veneer of "education", which includes many things not taught at school, like critical thinking, social skills, being widely read, broad general knowledge, the habit of trying to solve problems yourself, and many other features of people in "elite" positions.

For example, one might notice the strange preponderance of Jewish people in those "elite" positions, both academic and artistic and commercial and political. This is perhaps more easily understood when you know that the Jewish culture places enormous focus on educating the next generation and on critical thinking, probably because of thousands of years of history where Jews might be chased out of their homes by mobs with pitchforks and torches, and leave with nothing but what was in their heads. In that context, social mobility is total: you rise or fall to the level of what you can carry inside your skull.
