I don't think that it is possible in our country. Corruption can be limited but cannot be stopped. It was hard to admit but in my opinion, 70% our politicians are corrupt and the other 30% was not clean as well. They are doing things different thing like smuggling or other means to earn money by abusing their power while they were in position.I have given up to the recent generation. Maybe the generation after the millenials will be less or corrupt or even CLEAN.
