Elon Musk and Donald Trump have a plan for America... to get people making babies.  
 
The tech billionaire, Donald Trump’s soon-to-be government efficiency tsar, is a proponent of pronatalism, an emerging movement in US politics that says US citizens should be having more babies and that it’s their duty to do so.  
 
Niall Paterson is joined by our US correspondent Martha Kelner to deep-dive into Musk’s views and where they come from. Martha speaks to Errol Musk, Elon’s father, and one IVF doctor in America, who is expecting a boom in business.
