Given that the US's economy is utterly dependent on tourism, do they just not want to have money any more or something?

Because who in their right mind is ever going to travel there at the moment?

It’s hard to find an authoritative source with perfect data but it seems unanimous the US is in the bottom quintile in terms of share of GDP from tourism.

Almost all countries below the US have much more immediate concerns about physical safety.

The US's economy is definitely not "utterly dependent on tourism".
