That day is coming for the rest of American citizens, as well. An increasingly desperate FedGov will be coming for retirement plans and capital assets and won't take kindly to Americans trying to flee with their wealth.
I think you are exactly correct. Ordinary folks won’t be allowed to shelter their wealth outside of the US. The elites, of course, will be able able to do so in order to ‘facilitate international trade’ and other noble reasons.
In something related, I saw an article where Tim Tebow was intimidated into not speaking at a Baptist Church that preached that Homosexual Sex is wrong and that Islam promotes violence. First, a famous celebrity is intimidated into not losing his 7-figure financial stream....soon, it'll be ordinary Christians getting sued for evangelizing...it'll eventually end with the Jews being rounded up and murdered, like the minions of Satan have always done throughout history.
