There is so much difference between any two individuals. You are born at a place which you didn’t decide. You don’t decide your situation initially. Measuring or comparing people based on one metric is a total non-sense. There is so much inequality in the situations that we all face. You may be treated equally in front of the law, but excluding that, there is total chaos where we are learning the lessons prepared for each individual by unknown authors and publishers.
It’s all the individual experiences that decide our perspective towards this world.
