FATCA: Swatting Flies With Atom Bombs:

Possible inflation of the offshore tax evasion problem and the staggering costs of the Foreign Account Tax Compliance Act are causing even the most ardent advocates of information sharing and ending bank secrecy to question the U.S. approach.
“For the U.S. to ask countries around the world to spend billions in implementation costs to deliver less than $1 billion per year is, economically, complete nonsense,” said Martin Naville, CEO of the Swiss-American Chamber of Commerce. He referred to FATCA as the least considered program in history and “mind boggling” in its unilateralism. “The net value of FATCA for the U.S. is probably negative,” said Naville, who added that tax compliance is a must but that there are better ways to achieve it.

But it goes after Fat Cats! Don’t you get our clever pun? And besides, how can we go after international money launderers without making it a crime to commit personal finance abroad?
