The doors started closing after 9/11 already, Its also difficult now to setup an international phone/wire Xfer account. Also “off shore” accounts are eliminated. Even Switzerland obeys, The US has a huge influence worldwide in that regard, most people don’t believe it.
It's more difficult in a few ways, and so much easier in most ways. There may be a few more regs from the gov't in the way but it's the private sector that actually does the work. Back in '75 I tried to xfer $14k from New York to the US Canal Zone, and the CitiBank lost the money and it took them a month. These days I can go online and move that kind of money from the US to Lesotho if I want --3 or 4 days tops.
OK, these days the fees are higher ($40), but I used to have to pay that much for all the telephone calls and telex's to make the idiot bankers pay attention.
