That is just what the Thai Government and 'ruling class' want. If you dont understand English it is very difficult to learn objectively about the outside World and other countries' values such as Democracy, human rights, worker's rights, minimum wages, animal welfare, the environmental crisis, etc. Nor can they learn much about their own country's shortcomings. Most Thais cannot see past the end of their nationalistic noses. But hey! maybe they are better off like this.
