One of my odd observations in life is that when a society (and its education system) concentrates on developing strong individuals, the society ends up with strong communities.
Conversely, efforts that focus on developing the community at the expense of the individual often ends up diminishing the individual people and consequently results in a feeble community with widespread oppression and poverty.
This is not an absolute, but a trend.
I believe that there is merit to my observation because self awareness is endowed at the human level. Humans are self aware. The city is not.
Much of Western history has been defined by Plato's observation that the whole is greater than the sum of its parts. 5 + 5 = 10. 10 is greater than 5.
This observation plays out in some case. For example a working car has greater economic value than a pile of parts on the garage floor. However, this principle is not true for all objects. For example, were I to drive my car head first into your car, we would find that the sum of our two vehicle (the wreck) is not only worth less than the value of the two cars. It is a net negative value.
There are cases where the part is worth more than the whole. A new motor might be worth more than a rusted out Chevy Vega. Placing the new motor in the rusted out car diminishes the value of the motor.
The mathematics is not linear. There is complex interplay between individuals and their communities; however, concentrating on developing emotionally strong individuals who have strong reasoning skills and sound moral character does wonders in improving society.
It is a shame that the public education system fails to do this.
