While I agree that there are many other examples of selfish behavior by tourists in general, like it or not, SXM is a tourist based economy and even if a local's job isn't directly related to tourism, in almost all cases, their job is at least INdirectly affected by tourism.

As far as cruise ship passengers in general, their presence has very little effect on land visitors and while the money that comes from cruise visitors is concentrated in a few areas, the island as a whole needs cruise visitors.
