Perhaps having political dynasties (where the power and authority are being vested to smaller group of people) deter the purpose of having a constitutional republic. Therefore the type of government if political dynasty are rampant can be referred to as oligarchy, more like the game of thrones.
However, since the Philippines is a democratic country, where people decide how the community should be run, it is the judgement of the people that dictates what type of government they want to have. Being the genious Filipinos are, people in authority capitalized the weakness in our government system adding the knowledge that poverty is the root of all evil, and here we are today.
In Politician's point of view: Why would I let them learn how to be a fisherman if I can provide them fish and feed them in my hand. If they learn, they could take my position, they can become better than me. Why would I let that happen?
In Citizen's point of view: Why do I need a new leader if the previous one is already good enough. Sabi nga nila, kung ano ang puno sya din ang bunga. Perhaps if I prefer the new one it will not be much of a change in progress. And, he is giving freebies, who would not want to have freebies.
Clearly political dynasties prevent Change, and in this ever past paced world that we have, the only thing constant is Change. That is why people make a fuzz about political dynasty. Imagine, Jolo Revilla, the son of the infamous Bong Revilla Jr. A former actor (who is not good in acting), a former Barangay Captain and now the youngest vice governor in the history of the Philippines. What can this history maker do to improve the welfare of its poor constituents whom because of lack of proper education voted for him. Dogs will not bite the hands that feed them. So the same goes with other political dynasty. They may have made an impression to thier constituents, but they are not the only people who can think. More likely, there is someone out there with a sensible idea to run the government in every year or every decade. Forcing Someone down the throat of the people because there is no other else is to much.
Yes indeed politics is just a battle of evil and lesser evil. But improvement should not be taken for granted.
