Donald Trump won t tell you this on his Twitter feed.The last time the tourism industry in this country saw such a drop was in the decade after 9/11.And now, Trump is the reason why people don t want to come to America.Under President Obama, the tourism industry enjoyed a resurgence as the number of international visitors rose to 78 million in 2015, a 27 million increase from 2006.But that s imploding now as Trump s policies continue to scare the hell out of people around the globe.Trump s travel ban, his proposed border wall, his attacks on our allies, and his anti-immigrant nationalist policies have struck fear into international travelers who wish to come to the United States to tour the land of the free.According to Alternet,Frommer s, a prominent travel guide, notes that  the prestigious Travel Weekly magazine (as close to an  official  travel publication as they come) has set the decline in foreign tourism at 6.8 percent  for this year. ForwardKeys, which crunches travel numbers, points to a 6.5 percent downturn in international travel to the U.S. in the week after Trump attempted to issue the Muslim travel ban in January. During the same period, the company found reservations for U.S.-bound flights from Western Europe fell 14 percent and plunged 38 percent from across the Middle East. And a survey released this month by the Global Business Travel Association concluded  45 percent of European business travel professionals say they are less likely to schedule meetings or events in the U.S.,  according to the Los Angeles Times.Even white foreigners from Canada and Europe are choosing to stay away from the United States because of Donald Trump.And the impact will do a lot of damage to our economy, including a loss of jobs and a decrease in our gross domestic product.The loss of all those visitors could mean future problems for a sector on which more than 15 million people rely for employment. Oxford Economics suggests the toll may ultimately ripple beyond the travel industry, even reducing the U.S. gross domestic product by a few percentage points, per Market Watch.This will particularly affect cities and states on the coasts where popular destinations such as Los Angeles, Miami, and New York City are located. As stated above, the ripple effects could reach beyond the travel industry as the lack of tourism dollars will hurt the hotel industry, restaurants, airlines, retail stores, and any other industry that profits from tourism.So this is a big deal that will hurt our country as long as Trump remains in office.America s thriving $250 billion tourism industry is about to take a serious $7.4 billion hit because of Trump s policies. It s a huge setback on our economy and it s only going to get worse as Trump continues to attack Mexico and China.So just remember that while Trump continues to tout plans by automakers and other companies that were made way before he took office, the tourism bubble is about pop on his watch and his policies are directly to blame.Featured Image: Joe Raedle/Getty Images
