That’s maybe a part, but not the whole story.
Your (and your parents’, and your peers’) real and perceived economic circumstances and opportunities have a lot to do with what you’ll value and prioritize as an adult - how invested and loyal you’ll be in society. Every poor person we generate due to greedy decisions has a very high likelihood of being a destructive force back to us.
Now consider how many poor people were generated by black slavery, segregation, and explicit racism in America, and how, in a society, we all just swim around in the same trauma soup, deflecting pain towards one another.
