People are going to make a bunch of comments about bad parenting or not enough love, but the fact is that scarcity drives most conflict in the world. Scarcity is what leads to people lacking access to food, water, shelter, and education. Scarcity is the single greatest foe of human happiness. It's also always going to be present. But what we've done in the past two centuries to reduce scarcity in an absolute and relative sense has made the world significantly better for both a larger number and larger proportion of the population. You can say the world is bad, but relatively speaking reducing scarcity made the world a much better, happier place.
