Policy and parenting

are very similar, according to Russell Roberts:

But reviving an economy is more like parenting. There's no manual. If there were a parenting manual, every hospital would hand one out with every newborn. But there isn't a manual because each kid is different. And parents come to learn that they aren't really in charge. There's too much of the process they can't control. So great parenting isn't about doing whatever it takes. It's an art. It's about a set of principles and knowing which principle to apply in which situation. When to be tough. When to be soft. When to give a kid a do-over.

Even the most skilled parents make mistakes. Not because they don't understand what it takes to be a good parent. Not because they aren't committed to doing the job as well as it can humanly be done. But simply because there's no way of knowing what to do next.

Often what's called for in parenting is the exact opposite of whatever it takes--what's called for is doing nothing.
