First of all, everything goes up and down. Somehow in Thailand they think money keeps increasing infinitely. Newsflash, it actually could go down sometimes.
Second, why is it always that they have some plans, they take a careful look at them and always end up with the most difficult, least convenient option? And then, why do these people start moaning about people leaving or not coming here anymore?
Third, when enough tourists come, they want either more or they start moaning there are too many?
Fourth, if one of the problems is that other countries are cheaper, stop the dual pricing to overprice everything. Maybe just trick everyone into coming by cutting that foreigner price in half and let everyone pay the same. Then if Thai people complain, they can just explain that coming with a foreigner would normally result in paying the same price anyway. And if you stop the big signs where Thais and foreigners are separated by price, and make a sign for everyone, it's very likely that there won't be anyone who would complain.
Fifth, stop the greed. The fact that this is such big news here proves that it's all about greed greed greed. It's always big news how much money comes in from tourism here. They should stop jerking off to these numbers, because foreigners notice it and won't be attracted to that.
Sixth, they would only let in 'quality tourists'... However, literally every. single. article. On ASEANNow is about how a foreigner f's up here. Trashing a 7eleven, being naked on a beach, starting fights with police, causing traffic accidents, acting like morons.... How did they qualify for the quality tourist check? Other foreigners don't want to either put up with trash tourists, or bear the consequences of these trashy people's actions like being looked at negatively.
