replyYou forgot tourism which is their largest money maker.
replyTourism is relatively big there but only relatively to the population numbers. I'd argue gambling contributes more to the GDP, while tourism only keeps the light on on the economy. Tourism allows the citizens to make money but it's a small country so it doesn't scale. Gambling scales globally.

But the internet does, and it is 12% for gambling, against 15-25% for tourism (whichever source you believe).
