One of the best things I read was an 1889 essay by Andrew Carnegie called The Gospel of Wealth. It makes the case that the wealthy have a responsibility to return their resources to society, a radical idea at the time that laid the groundwork for philanthropy as we know it today.
In the essay’s most famous line, Carnegie argues that “the man who dies thus rich dies disgraced.” I have spent a lot of time thinking about that quote lately. People will say a lot of things about me when I die, but I am determined that “he died rich” will not be one of them.
It’s not really about lowering birth rates directly it’s about removing the perceived need for higher birth rates.
There are quite a lot of studies that show that even in countries where infant mortality is now manageable it still takes several generations before that trickles down to the population and they stop having 15 kids as standard. Also lack of sexual education doesn’t help.
