After carefully considering the article, I disagree with the opinion that 'Two-Tier' pricing is harmful to Thailand's tourism industry because Frist of all, Thailand is a developing countries, so it is deserved to keep tourists than people in the country for example tourists visit a temple or world heritage sites to collect more Thai people because tourists come mainly from the developed countries and many tourists come form rich countries. Secondly, Most tourists, Thailand's Government does not tax for example, Thai people taxable State income, career each month. Finally, Thai people should have many rights more than foreign people or tourists for example, Thai people can go to Wad Phra Kaew or museum. As you can see from the reasons above I disagree with the opinion that 'Two-Tier' pricing is harmful to Thailand's tourism industry. However, the price charged to the foreign tourists should not be too high, should be in proper quantity.
