No, I wouldn’t solely blame Kim Jong Un if a soldier from NK kills a member of my family. The ultimate goal of a totalitarian regime is to convince people that they are powerless, that they need a leader to guide them. This takes away all agency and responsibility (where it matters).
Don’t fall into the same trap. Everyone is an individual, everyone can and should learn. Everyone is ultimately responsible for their life (excluding situations where people are physically constrained by an abuser).
Blaming the “billionaires” is a fruitless endeavor. Do you think if we get rid of billionaires we will automatically live in a just society? There will always be people with more power, billionaires or not.
Worldwide, I am in the 1%. You are most likely too. For a lower class family in Pakistan you are a billionaire.
