The problems is that if the Feds want this pot of gold, they will have to go through a minefield. Never mind the political and possible armed resistance to acheive such an aim. If nationalization is seriously considered, the market value of these investments will plunge, so there will be much less to confiscate. There would be a rush to pull out money from these funds and banks in general. Overseas investors would evaporate overnight. A stock market crash would also destabliize the currency, the government would have trouble borrowing money leading to inflation. Markets would be very unstable world wide and civil strife would ensue.
So if the government tries to tamper with these funds even in a small way, all hell will break lose.
IMHO, if Barry gets a 2nd term, he’ll just seize the accounts via Executive Order.
The Obots will nod and say “thank you sir, may I have another?”
