Is tourism has been a culprit in commodifying cultures and traditions?

Due to too many tourists come to visit the tribes in Chiang Mai, many hill tribes now are suffering from a loss of their culture such as selling souvenirs that had been made some changes according to the tourists’ preferences or demands.

By tradition, the hill tribes are supposed to live on their own without much influence from the outside world. However, today, many hill tribes are open their homes to tourists to attract them so as to earn some income from them. Although it is a good thing that people can exchange knowledge about their cultures, the hill tribes share their cultures hoping something in return such as money from the tourists. This may leave a bad impression on their cultures.
