Time is short. Every aspect I have learned about was already well under way at the time I learned of them. Various groups of people around the world have had their accounts closed or frozen for a number of years due to where they were born (Bank lockout for “Accidental Americans”) and in the US for businesses that were/are perfectly legal but where of a nature those in government did not like. With the advance in tech, the use I use Big Data, IoT and FinTech, the change can easily come as quickly as a switch turning off the lights. Too late to do anything then. That wait and see tactic was what experts suggested for FATCA. I have now had every transaction I make in Japan where I have live for over 20 years reported to the US since at least as early as June 2014. I had to provide my US SSN# to open a new bank account in Japan a few years back, the first time in 20 years living and banking here. But the worst of this wait until it get really bad mentality is that my children, born inn japan to a Japanese mother are also subject to US tax and reporting g requirements die to the fact that one of their parents was a US citizen at the time of their birth. The consequences a waiting are far greater than we know until it is too late to prevent them. The effort to correct these are far greater than the what would have been required to prevent them. As firefighters say, an ounce of prevention is worth tons of water. Yet, no one wants to expend an ounce of prevention until tons of water are required.
