Those corruption were already there before duterte became president. The only thing right now is that itcis being revailed and unlike before where everything is being hidden because of the political support. Worsen? Lol you are not in the Philippines why not come here and experience living before saying
Duterte is similar to Trump. He is trying quite hard to fulfill his campaign promises. But it is not going to happen overnight. Eradicating corruption from a country such as the Philippines can take many years, if not decades.
It won't be that easy, but at least he is trying. We all know how hard it is for the Filipino people to see that and I hope they see that it's constantly changing and making it better. Evil can't be eradicated, it can be lessened. I hope it happens though, complete peace.
