Nonsense! Don't you know that the rich tourists don't spend more than lower income tourists? Individually, they eat the same amount of food and drink the same amount of wines and beers at the hotels and restaurants. What else are there for them to spend their money on that cost more than what average tourists spend? Maybe they play more rounds of golf. Also, they could arrive in their private jets and mega-yachts fewer times than the commercial aircraft bring plane-load of visitors.
