It's only a tax evasion concern in the first place because the US started the trend of hoovering up wealth generated in other countries, which in-context still sounds like US overreach. They weren't arguing for anyone's right to be corrupt in the first place though. If US citizens really have to pay extra taxes and have arduous reporting requirements then so be it, but why is the rest of the world dragged into that mess? This isn't a "dirty banks" issue; it's nearly impossible to get a bank account at any reputable institution as a US citizen abroad just because of the PITA of the reporting requirements. It's a mediocre law from questionable authority.
