I don’t blame Saverin one damn bit for giving up his U.S. citizenship to avoid the excessive taxes of Uncle Shark.
The federal regime in Washington wastes trillions of dollars on their insane bullshit, year in, year out. Saverin owes them nothing.
If anything, Zuckerberg and Saverin ought to run the federal government since they obviously understand running a business better than the government does.
I agree, it's his life. But that being said if he needs the USA's help in the future if the STHF in whatever country he is in he needs to be be given the finger.
