I know of an immigrant couple that although they were green card holders and have been living in the US for about 10 years, they decided to pack up and leave to Europe (to another foreign country, not to their native country) and one of the reasons they said was that they didn't want their tax money to support an immoral government and military. It seemed weird to me at the time, was the first time I ever heard someone say that for a reason to leave the US but they seemed dead serious and knowing them I have no reason to belief they were lying...
