At least they used to do so until Soros's allies began to fire back with accusations of anti-Semitism, which had the effect of muting the complaints.
1956 and is now an American citizen. The sources of at least some of his wealth are somewhat controversial. He made over $1 billion in 1992 by selling short $10 billion in British pounds sterling, leading to the media dubbing him "the man who broke the bank of England."
