If our government opt Federalism, then there'll be decentralization of powers, budget, and interests. Each province will be given the discretion to progress, to allocate budget, and to be given freedom to implement ordinances. In simple words: It'll foster self-reliance. No longer Mindanao and other provinces be at the backseat of government's budget allocation, they'll be given all the necessity to look after themselves.
While Parliamentary, I suppose, strengthen political parties. The likes of Gloria, Meriam Defensor Santiago and other
balimbing politicos will be descredited, worst ostracized. The shot: it'll foster strong, established, and CONSISTENT political parties to make it to the Council who will rule the whole state.
So there. I hope you can suggest what you think is best for our country should you think we need, bady need to facelift our current system.
