Implode-o-Meter News - The Shocking Real Reason for FATCA, and What Comes Next

FATCA's real purpose is not to collect money, but rather to pave the way for a global FATCA, informally known as GATCA... the central planners at the G20 and OECD devised what they call a new "global standard" of automatic financial information exchange between governments (i.e., GATCA) modeled on the US's FATCA. In other words, unaccountable bureaucrats from these supranational institutions are foisting upon the world a FATCA on steroids.
... it's highly probably that the OECD, the G20, and others will sanction or otherwise blackmail countries that don't comply with GATCA. The pressure will likely be too enormous for the vast majority of countries to bear.

In the end, this means a permanent record of every penny you have ever earned, saved, borrowed, or spent anywhere in the world will be available in an instant to be analyzed and scrutinized, and shared with any number of local and global government agencies, all regardless of any actual or suspected wrongdoing.
