Sorry to take this off topic, but I just could not let this one stand unchallenged. Kennedy, Bush, etc in terms of 'dynastic' families have at least as much to do with wealth, connections, and opportunity as they do with 'expectations'. Expectation and nurture are very important, but I think environment and opportunity are equally important. Being educated in a good environment by good teachers with good resources and good nutrition leads to better outcomes than hunger, bad teachers with few resources, and bad neighborhoods.
