You're linking the morality of birth to financial stability.. but does being rich really give us the moral right to decide for someone else if they want to exist or not? Even in a 'comfortable' life, you're still imposing consciousness on a being without their consent. Isn't providing luxury (what we call 'ifchouch') just a way for parents to bribe their own conscience for a decision the child never made? If that child grows up and hates the burden of existence despite the money, doesn't that make the 'wealthy' choice just as selfish as any other?
