If I was to get a child and I'm in debt, the child would be growing up in a bad spot. So have the child not be born, or have the child live in misery? Why should the child suffer with parents who couldn't afford to take care of the child.
People are always indebted in some way.
Poverty is better than death.
Had Einstein never been born we would not have satellites, nor a GPS system. Had Feynman never been born we would not have solar panels and most of theories in quantum mechanics. Had Morgan Freeman never been we would not have an amazing God character. Must I go on?
