This is really complicated since somehow government is benefiting thru taxes they can get also possible kick backs from those casino owners.
If we really believe that’s the case, then we need to elect an honest president in the next election. As the head of state, he can make decisions to investigate and minimize corruption. It all starts from the top, if the president isn’t doing anything because he’s also benefiting, then nothing will ever change.
The problem is that it's deeply rooted already, now they have the son of a former dictator and then the head of the speakership of their congress is already blood related and reports say that he is paying politicians to stay with them and go against the former president which is in Hague and the daughter which is the vice-president today who they wanted to impeached.
So even if we talk the head, there are still a lot of politicians that might take advantage of this illegal gambling or even legal gambling that operates under the country. That's why it will take a lot on who is going to lead the country next to eliminate corruption, not just gambling.
