Those who observe can make connections. Everything starts from the power to understand this law of causality, but in a simple, popular way.
Cicero said in "The Six Sins of Man", among other things, that sin that we have been repeating for centuries is:

the family in which we were born, therefore the "start" position that we had in life (no matter how we cry, we can not change that)
politics - and the fact that we have corrupt politicians; unless we are in the system and we can have a direct influence, the only thing we can do is vote and see for life
the economic system taken globally (the eternal "crisis" we blame) - we can influence it too little, so we can only wonder how we can adapt

injustice and social inequality
