The English language should be prioritized as it is the mostly known language in the world. If armed with knowledge in the said language, communication would be easily done with foreigners. Although the native language is important as it is the primary language of each person, it would be best to focus on a new field of knowledge (such as learning English) rather than studying something which you are born with.
Yet of course, institutions should also teach its mother tongue to equalize the value of education in the country.
In my opinion, any Filipinos are having a hard time speaking in English. I think you can only speak fluent english if you study in a good school (private schools, etc) or if you speak english in your house. I think they should teach english in school more since you can learn Filipino/Tagalog easily because you speak it everyday.
English is a global language. We should put emphasis on its importance and contribution to the country. You don't have to trade your culture and heritage to learn English. I've been taught English in schools , but doesn't really affect any negative drawbacks it may have...It's a nice language to have. Spanish, French, German, Italian etc... Are all beautiful languages. Just respect it as our own.
English is only learned because the current state of global economy and geopolitics tends to be in favor the powerful English-speaking countries. Imagine if China had more influence in modern Philippines, it would then be more beneficial for Filipinos to learn Chinese instead of English. Or if the Germans won the second world war, the so called 'global language' would be German. Learning other languages besides English gives you more business/career options if you are planning to work overseas or have foreign business connections. No superpower country can last forever. Empires rise and fall.
About what language to prioritize teaching in schools, I would daresay that the current thinking that Filipino language only includes Tagalog is wrong (it is a sign of Imperial Manila). Bisaya language is also popular so I think it should be taught also in schools nationwide alongside the Tagalog language, other native languages too but I am not familiar with those. Korean language is also popular because of K-pop and K-drama so it would be a good optional course.
I am thinking why Filipino laws are written in English. I think this is a mistake. The laws are made for Filipinos to understand, not for foreigners. The laws should be first written in Filipino but keep an English translation available for foreigners in the country. I think this is also one reason why there are those who, by ignorance, disobey the law in our country, because they can't read English.
If we are to aim for the most spoken language in the world then we should be learning Chinese instead. I believe English should be learned but not prioritized. If we are to look at the world superpowers, say Japan or China, they do not subscribe greatly to languages other than their own. In all their undertakings they prefer their native tongue because it is what they are used to. They see to it that their messages cut through all walks of life in their society. It is important for them that they answer to the needs of their countrymen. We cannot possibly aim for national development if we do not look into ourselves first. We have not yet addressed national concerns and we always look outside to answer the problems we have inside. Capability development for our country must be established first. Most of our problems are specific only to our culture and to look outside is to avoid the problems.
As Jose Rizal once said "He who does not love his own language is worse than a smelly fish." So the Filipinos who said voted yes is worse than a smelly fish. Also I think Filipinos should aspire to make Filipino the universal language though nearly impossible due to the fact not much even knows about the Philippines.
All cultures are based around a language! This would be the equivalent to what Americans did to the Hawaiians, what the French did to the Africans, and there's many other events in history. All of these places have lost a large amount of their culture, which defines them as them. This is what causes languages to become extinct which has been happening lately in recent years.
One of these days, when you've English too far, you'll realise how fast the youth in your country are forgetting their native language. Not forgetting how to speak it, of course, but experiencing a general drop in language proficiency because of English. In Hong Kong, the British have left Chinese proficiency in Hong Kong a mess. Westernised sentences are ubiquitous and highly annoying, and most people forget all their Classical Chinese after leaving school. Please don't follow our footsteps - stress the importance of English, but don't put Tagalog behind English.
