Any large reduction in corruption will require a mind set change in society and aggressive enforcement of laws.  It would be a decade(s) long change.   Right now society at large seems to consider corruption as a bad thing, but at the same time, have the feeling they can do nothing about it.

The government cracking down on corruption by rooting out corrupt government officials in a very open public campaign might be a good start....and this is not to imply there is not plenty of corruption in the private sector  also.  But the government needs to start cleaning its own house before it tries to focus on cleaning up the private sector house.  When the private sector sees the government cleaning its own house, the private sector will start doing some cleaning on its own.

Ain't no easy or quick answers to greatly reducing corruption...but answers do exists...and the answers will probably take a generation or more to implement.

Until early '90, Italy used to have one of the highest level of corruption in the world, especially within the Government sector.
It took almost a decade and plenty of high profile court cases, incarcerations of "untouchable", confiscation of family assets, banning of political parties and executives, reshuffling within army and police....the fall of the gods, in a word.
The whole process went under the name "Tangentopoli" (The City of Bribes) and saw Italy moving to a better and modern form of society.
It was painful but absolutely necessary.
The Italians were fed up with the system and it took a group of energetic and committed lawyers and judges to bring it down [unfortunately, these very same people established a new form of power controlling the State].
Such revolution was supported in Italy by the education of people in politics and civil rights, values that Thai people are lacking greatly!
I see Thais complaining about corruption and at the same time, they embrace it as part of their normal life....
