There was a Monty Python skit where a banker said that the solution to Britain’s fiscal woes was to tax all foreigners abroad. That came to mind when I read a story on a free-speech lawsuit against the federal government by the usual suspects for denying visas to foreigners based on their political beliefs. Frankly, we need to be doing a lot more of this; while it’s a tool we should employ with caution for prudential reasons, a provision sponsored by Barney Frank in the 1990 immigration law inappropriately ties the government’s hands. I published a long overview of this issue a few months ago, but the basic point is not complicated: Entering the United States is a privilege, not a right, and Congress and the president have the right to exclude any foreigner from coming here for any reason whatsoever.
