World Travel & Tourism Council Travel & Tourism Economic Impact 2017 United States "Visitor exports generated USD 212.3bn, 9.5% of total exports in 2016. This is forecast to fall by 0.6% in 2017, and grow by 3.9% pa, from 2017-2027, to USD 309.7bn in 2027, 9.3% of total." [0] US GDP in 2016 was USD 18624bn. [1] So I suppose it's only 1.1% of GDP. What's USD 212.3bn between frenemies huh? ;-) [0] https://www.wttc.org/…
Exactly. The complete loss of international tourism (and realistically there wouldn’t ever be a complete loss unless we closed the border) would result in a 1% loss for the US GDP/economy. Not nothing, but certainly not devastating.
Tourism generated 1% of the GDP but you don't know the impact on other industries, you haven't seen figures on lost of tax revenue from jobs lost, cost of retraining people to find new jobs, burden on society from unemployment, etc.
I don't think that tourism will cease in the US but any downturn on it has larger effects than just the GDP figure brought by the industry itself.
Of course, if you only care about numbers the dollar figure won't look much, if you care about the lives affected by idiotic policies then you have to look deeper.
