As long as they can't get a hold of the oil prices and rising other costs the economy is going to keep faultering. Food prices are going to continue to rise, Gas prices keep on showing trends of rising again this summer, some say past the $4 mark. Which means the cost to travel, deliver goods, and electric will continue to rise. Unchecked we will continue to have our dollor fall off in value. Also when we keep on just printing more and more money to fund the war costs our dollor goes down. As far as the crashing goes on the stock market, no it can't crash, but it can keep falling for a long time.
As far as international currancy...Look at our friends to the north, they are what now....$1.38 vs our $1 now? All my life we were always about $1.10 us vs $1 canada and now we are 38% behind?
