Hedge fund investor and Harvard grad John Paulson just gifted the 379-year-old university its largest donation ever to rename the School of Engineering and Applied Sciences after him. But his charity has some fuming over the windfall going to America’s richest school — with its $36 billion endowment — while others struggle. “If billionaires don’t step up, Harvard will soon be down to its last $30 billion,” tweeted Malcolm Gladwell. Perhaps a little mocking will help future donors look beyond the Ivies.
