Actual Attempts

FinCEN ( Financial Crimes Enforcement Network) have in quick succession proposed two separate recommendations for combating money laundering, both in the real estate market and financial advisors. There's obvious world events that spurred this on, but since the last truly earth shattering change to such laws, which depending on perspective was either ten or twenty years ago, this is at least something of an attempt.

It's still largely held back by the same thing that generally holds with all laws, if no one is looking and the person simply doesn't care there's nothing actually stopping them from doing it only the threat of consequences when they slip up, which is still better than nothing.

On a score of 1 to 10, it ranks around a six or seven at least.
