This statement cannot be allowed to stand uncontested. It suggests that everyone is exactly where they ought to be, that all bullying and harassment and isolation that keeps people from reaching their potential is right and just.
Real oppression, an experience the US professional middle class is largely spared of, the type experienced by the citizens of Venezuela or the people currently being held in Xinjiang re-education camps, is truly insurmountable and requires large macro shifts to institute change. To suggest individual bullying, harassment and isolation are counted as so insurmountable to a person's theoretical "potential" that the environment must change first to prompt it, is an illustration of the deep self-absorption very few people have the privilege to experience.
Nothing is right or just in this context.
Surely Venezuela could have less social mobility, but it isn't actually that great in the west.
