The Philippines is a third world country same to other third world countries where the problem are on the root, but people only fix the top, hence even someone remove the top, the root can grow and it's ended up the same.
That cycle will continue if those corrupt will not get punish or if your countrymen will continue to elect those corrupt official. To only stop this situation to keep happening better choose the right leader and don't choose those traditional corrupted minded people in the seat.
How it can be possible to choose the right leader when applying to be a leader require a lot of money and the winner is the one who give money to the voters? There's no way to change it except a huge nuclear explosion happen on the country that make people have to build from zero or other country takes their lands.
