I disagree.
Because of Covid I haven't been here for the past 2 years, but overall, comparing now with 10 years ago things here have vastly improved. I refer to Roi Et and Jomtien. Pavements have been repaired, new roads built (RE) recreation areas cleaned up and improved. In Jomtien the beaches have been massively expanded, trees planted and generally it's much cleaner and tidier than in the past. A huge improvement over the Thaksin years. A new and friendly Immigration Office in RE is also great. Sure, the corruption still goes on but I read encouraging signs that some changes are announced even if not implemented.
