The folks over at MetaFilter reminded me of the “Permanent Tourist” (a.k.a. “Prior Taxpayer”).
In a nutshell, a PT merely arranges his or her paperwork in such a way that all governments consider him a tourist. A person who is just “Passing Through.” The advantage is that being thought of by government officials as a person who is merely “Parked Temporarily,” a PT is not subjected to taxes, military service, lawsuits, or persecution for partaking in innocent but forbidden pursuits or pleasures.
I’m sure there are disadvantages to being a refugee without a country, too, but it seems to fit some people just fine, and there’s a heartstring of mine that tends to hum in harmonic sympathy when the topic comes up.
Of course, Uncle Sam wants to get his hands on his share of your money no matter where you earn it, so this is no panacaea (or, anyway, you’ve gotta stay on guard).
