Can trying to be safe actually be dangerous? Greg Ip, chief economics commentator of the Wall Street Journal, says yes in his new book, Foolproof: How Safety Can be Dangerous and How Danger Makes Us Safe. When we try to be too safe, we become complacent. Ip argues that the stability of the ‘80s and ‘90s made us take risks that culminated in the 2008 disaster. Being too safe can also explain non-economic problems such as forest fires and football injuries. Ip also shares his thoughts on Fed policy and the possibility of a “helicopter drop” of money.
