That's a good point. I believe Jordan charges foreigners a much higher rate for to see tourist attractions. But, visitors don't usually stay in Jordan for more than a couple of weeks. I think if a country let's someone in only for them to find out that they're not welcome there - they're probably not going back again. It's better to know that a place is very expensive to visit up front, or - like Bhutan - there are very few tourist permits given out.
