It is not only this tax who makes the problems, we pay already the same amount being departure tax, add to that the exorbitant entrance fees to visit a park, or the 300% tax on wine, all these things together make it less attractive to visit this country......not to mention the extreme air pollution.
But especially continue this way Thailand, you can be sure that sooner or later there will be fewer and fewer tourist, even the better-off tourists will definitely stay away.
