It's crazy that you accuse the person you're replying to of being lucky, when your comment is the epitome of privilege. Since the year 2000, child mortality rates declined over 2x in Africa and Asia. That is millions of children who, in another era, wouldn't have had the opportunity to grow up.

I don't think your complaints about your life are true, see my other comment, but even if they were they make no impact in the big picture of "has the world gotten better or worse."
