Being that unlike Greece, the U.S.A. has control over its currency,
Personally I think the fed can print as much money and buy treasuries to keep interest rates low for however long it takes.
Eventually the economy will find its footing and yes after every bad recession they always say the same thing (The U.S.A. best times are behind it), I remember being in a Swiss airport paying 12 dollars for a coffee and donut in 1995 and being scolded by the waitress that the U.S.A’s time was behind it and that we had to learn to accept our place (well it was something like that).
