A wealth tax for the deficit?

ARNOLD KLING:

Other countries that have defaulted have not had the option of enacting wealth taxes. When you are in a banana republic with shaky government finances and you have a lot of wealth, you send that wealth over to the United States, where your government cannot get to it. That "safe haven" motive is what keeps the dollar so strong. Anyway, by the time the banana republic gets around to enacting a wealth tax, all the wealth has fled the country and there is nothing left to tax. So the banana republic defaults.
