It’s rhetoric time! With the world gradually turning to shit with more and more incidences of violence, poverty, abuse at all levels, why do many people still want to bring children into a world that is generally going to destroy and subjugate who they are? Is this a selfish desire to just want babies ? Is it more a biological function which will continue regardless of the non-sensical outcomes? Any ideas?
Your fundamental premise is wrong. The world is getting better under almost any criterion you can think of. You need to read Pinker's "Enlightenment Now" to get a better perspective on the state of things and a better outlook on life.
I agree, Pinker’s study is certainly engaging with statics to support.
