Matt Ridley: Doing good by doing well

Mark Zuckerberg and his wife Priscilla Chan marked the birth of their daughter Max by promising to donate 99 per cent of their Facebook shares during their lifetimes to support good causes. For this they were pilloried by some. The economist Thomas Piketty called it a “big joke”. For author Linsey McGoey it was “business as usual, rebranding as philanthropy, and announced with a deceptive air of selflessness”.

We have reached new depths of cynicism when a couple say in a letter to their newborn child that “our hopes for your generation focus on two ideas: advancing human potential and promoting equality” and some people can only sneer.
