One thing you can say about DC comics is that they are trendy. There is a lot of buzz among the "hard money" types about the desirability to revoke one's US Citizenship. But for Superman—the stand-up guy for truth, justice, and the American way—to give up his citizenship is shocking. I know what you are thinking. He was born on Krypton and has no American birth certificate. While it is true he can't run for president, Superman is "as American as apple pie." In fact he was given citizenship in the Kennedy administration—so he could give it up if he wished. (Yes I know, Clark Kent and Lois Lane never age, but hey, no comic is perfect.)
Is Superman right? Should one renounce one's US citizenship? Many people could do it if they wished. All that is required is a new country. You can become a resident of Paraguay, but not a citizen, by depositing $5000 dollars in the Bank. St Kitt and Neva (and who would not want to live in a tropical paradise!) require $200,000 to $400,000 in investment in the country. I am eligible for citizenship in Russia as my wife is a citizen. But the big flaw in any of these plans is the question, "Why is anyplace else any better?"
Since the whole world is a part of Babylon the Great, there is really no place to go. The analogies people draw are not valid. While it is true that 1/2 of pre-WWII Germany's Jews saw "the handwriting on the wall" and left, is that a valid analogy? Yes, the 1/2 that did not leave died in concentration camps. But while the paranoia of the supposed FEMA camps is driving a lot of immigration, is this really a valid concern? While I see no reason for those able to get a second legal passport not to do so, I also see no reason to leave one part of Babylon the Great for another. Of far greater importance is to leave Babylon spiritually. Do you really think that if troubling times come, being a foreigner in another country is really a good choice?
So while it might be tempting to make the ultimate political point, it seems pointless to me. Prudence might indicate that those who are eligible for a second passport get one. But remember that although Superman gave up his citizenship, Clark Kent did not.
