Walter Oi once told me that the two most important choices you make in life are your wife and your parents. By the latter "choice" he meant that your parents have a big impact on who you turn out to be. One of the important things included in that influence is where you are born and grow up. I am so fortunate to be born and raised in the United States. (HT: Donald Luskin) I think most immigrants to the US understand that—the overwhelming reason they come to the United States is for their children.
