Its r national language here in the Phillipines

What are the factors in the slow development of our national language?

Help very much appreciated :/ .
It's for research paper. I considered the argument of Filipino being the national language since not everyone really agrees but when I got to the abstract draft, I don't know what to write....so ideas?

yeah,how come tagalog is the national language of the philippines.?when the visayas and mindanao and also part of palawan speak a language similar to cebuano....no offense:)

*For me, the Philippine government do not pay attention with regards to the distribution of Philippine literature in the country. Why?

* We all know that Philippine literature helps a lot to raise our national language. How?

*Nowadays, Filipino language is being snobbed by Filipinos themselves because they weren't able to use it especially to those educated people. Why?

*Some Filipinos are also fond of reading materials which are written in English rather than in FIlipino. Why?

*Before, some Filipinos patronizes the Philippine literature, but now, they do not want to read more of it & spend their time with it. Why?
