The number of foreign visitors to the United States has plummeted since the September 11, 2001 attacks on New York and Washington because foreigners don't feel welcome, tourism professionals said Thursday.
"Since September 11, 2001, the United States has experienced a 17 percent decline in overseas travel, costing America 94 billion dollars in lost visitor spending, nearly 200,000 jobs and 16 billion dollars in lost tax revenue," the Discover America advocacy campaign said in a statement.
Is that the dollar has declined about 40% with respect to the pound and the euro and the loonie (very rough number).
