According to this numerical table, the PAVED ROAD in Thailand is close to the one of the United States or what? Let me know.
Interesting data but it does not tell us how much a country has developed. It indicates that Thai politicians know only how to develop only one thing and that is to built road.
It's the title of your thread that is a provocation (ເປັນຕາອາຍບໍ່). It shows you are a bit ignorant because you do not take into account a lot of factors between Laos and the other countries. If you also show Cambodia and Burma, I would understand why should we be ashamed, and of what.
Don't worry too much. It's an exchange of opinions.
