Why do most Asians speak English more fluently than that of other ethnic groups?

Like the previous poster, I humbly feel that our seeming fluency in English stems from the fact that it is our second language. In our country, for instance, the english language is really given premium, and our primary language--Filipino--even takes the backseat at times. Our constitution even sanctions the use of the english language, perhaps because the framers of our constitution recognized the importance of english in the global arena, since, after all, it's considered the universal language. English likewise is very instrumental in determining whether a job applicant would be hired by a multinational company here in our country. Having a very good grasp of english could very well be one's ticket to a good job and, thus, we have to be fluent in english. That's just my 2 cents, anyway.

it is because they consider english as their second language. they study for it.

because they got the mental capacity to do so.
