I believe about 18MM Americans work in the tourist-related industry in the US. With the new totalitarian visitor rules, many Europeans are thinking if they really NEED to return to the US. Yes, it was a great visit, great country, great people, but I get less hassled when I enter a third world dictatorship and some of them offer great things to Tourists too. So maybe my next trip is to such a Country, or I go to Canada, Mexico, St.Lucia etc.
I have European friends who refuse to visit now that they need to replace their perfectly valid EU passport for a new one as required by the US Government if they were to return to the usa. SO they say "Screw it, you come over here"
INS/ICE is endangering Jobs in the US, but I guess we'll endure anything in the name of "SECURITY"
