Dr. Spock on spanking

I saw anti-spanking fanatic Jordan Riak on Fox News a few days ago. The last edition of Dr. Spock's Baby and Child Care said:

There are several reasons to avoid physical punishment. It teaches children that the larger, stronger person has the power to get his way, whether or not he is in the right. Some spanked children then feel quite justified in beating up on smaller ones. The American tradition of spanking may be one reason there is much more violence in our country than in any other comparable nation.

It is a fact that the larger, stronger person usually has the power to get his way. Yes, children should learn that message. No, it does not explain violent crime in America.
